sys-boot/gnu-efi: Add custom-cflags flag and prevent avx instructions
Building gnu-efi with custom compiler flags is risky at best and should
generally be avoided.
Nevertheless, if custom flags are used, we need to make sure no avx instructions
are generated as those cause a non-functional gnu-efi build. This is only
required for >= 3.0.5 as prior to this, "-mno-sse" was used which also implied
no avx.
Fixes bug #619628.
