Remove sys-devel/binutils

binutils-2.20.1-loongson2f.patch is included in at least 2.21.1.
binutils-mips-tls.patch is not in 2.22 but I'm not sure that the patch
is correct, nor have I experienced any problems without it.

Remove the outdated copy of cvs.eclass that was copied for binutils-9999
as well.

-Subject: [PATCH] [PATCH] Fixups of Loongson2F
-
-(This v4 revision incorporates with the feedbacks from Richard
- Sandiford, Zhang Fuxin, Maciej W. Rozycki, Alfred M. Szmidt and Yan
- Hua, Thanks goes to them!)
-
-This patch adds two new options for binutils: -mfix-loongson2f-nop and
--mfix-loongson2f-jump to work around the NOP and Jump instruction Issues of
-Loongson2F.
-
--mfix-loongson2f-nop replaces the original NOP instructions by "or at,at,zero"
-to work around the NOP issue. Without it, under extreme cases, cpu might
-deadlock.(e.g. some have seen this with binutils 2.18, ld dies when compiling).
-
-The NOP issue has been solved in latest loongson2f batches, but this fix has no
-side effect to them since the "or at,at,zero" is also a dummy instruction.
-
--mfix-loongson2f-jump inserts three instructions before the J,JR,JALR
-instructions to eliminate instruction fetch from outside 256M region to work
-around the JUMP instructions issue(only with some specific external chips, such
-as CS5536.). Without it, under extreme cases, kernel may hang/crash with
-unpredictable memory access. This fix may bring us with some potential
-overhead. This issue has been solved in latest loongson2f batches.
-
-These two fixes are recommended when compiling kernel, but only the
-first one is needed to compile applications. That's why I split them out
-into two options, not just one -fix-loongson2f. More detailed
-explanation about them are given by Zhang Fuxin(one of the Loongson2F
-designers) as follows:
-
-  - The NOP issue
-
-"The nature of the erratum is deeply related to the microarchitecture of
-Loongson-2. It uses roughly a 4-way superscalar dynamically scheduled core,
-instructions are excuted as much as possible in parallel with technics like
-branch prediction etc. We use a 8-entry internal branch prediction queue to
-keep track of each predicted branches, if some branches are proved to be
-wrongly predicted, all the instructions following it will be cancelled,together
-with the resources used by them, including the registers used for renaming, and
-the queue entry will be freeed. There is a bug that might cause a hang when the
-queue is full(some resources might been leaked due to conflict branch entries),
-the workaround is to reduce the possiblity of branch queue full by using
-renaming registers(they are also limited, can prevent too many simutaneos
-branches). In theory this is still not enough to fully eliminate possible
-hangs, but the possiblity is extremely low now and hard to be hit in real
-code."
-
-  - The JUMP instructions issue
-
-"The Loongson-2 series processors have quite complex micro-architecture, it will
-try to execute instructions from the predicated branch of coming instruction
-stream before they are confirmed to be run, if the predication of branch
-direction is proved wrong later, the instructions will be cancelled, but if the
-instructions is a read from memory, the read action might not be cancelled(but
-the changes to register will) to enable some prefetch. This will lead to some
-problems when compining with some chipsets. E.g. the AMD CS5536 used in
-Yeeloong/Fuloong will hang if it gets an address in the physical address range
-of 0x100000-0x200000(might be more other ranges). Speculative reads can perform
-read at any address in theory(due to wrong prediction of branch directions and
-the use of branch target buffer), thus in very few occasions they might cause a
-hard lock of the machine.
-
-To prevent this, we need to prevent some addresses from entering branch
-target buffers. A way to do this is that to modify all jump targets, e.g.,
-     calulations of t9
-     ...
-     jalr t9  =>
-     calculations of t9
-     or t9, t9, 0x80000000;  // to make sure t9 is in kseg0
-     jalr t9
-Of course, we have to consider 64/32bit, and modules addresses etc.
-
-This only need to be performed on kernel code, because only there we can have
-accesses not translated/limited by TLB. For user code, it is impossible to
-generate accesses to unwanted physical address. So it is safe.
-
-Also, to prevent addresses generated by user mode code to be used by the
-kernel, we add a few empty jumps to flush the BTB upon entrance to kernel."
