PowerPC: fix backtrace to handle signal trampolines
This patch fixes backtrace for PPC32 and PPC64 to correctly handle
signal trampolines. The 'debug/tst-backtrace6.c' also check for
SA_SIGINFO handling, where is triggers another vDSO symbols for PPC32.

 /* This macro is needed for PPC64 to return a skeleton OPD entry of a vDSO
    symbol.  This works because _dl_vdso_vsym always return the function
    address, and no vDSO symbols use the TOC or chain pointers from the OPD
