dev-util/google-perftools: revbump 2.7, fix ppc64le bugs

it was not building libprofiler on ppc64le

..Could not find the PC.  Will not try to compile libprofiler..."

add debian patch, now it builds fine
..checking how to access the program counter from a struct ucontext...
uc_mcontext.gp_regs[PT_NIP]

also on ppc64 it does not link to libunwind, make dep optional
