PowerPC: Add systemtap static probe points in setjmp/longjmp
This patch add static probes for setjmp/longjmp in the way gdb expects,fixing the gdb.base/longjmp.exp gdb testcases. It changes the symbol_name and use macros to to avoid change the probe names and ending up adding more logic on GDB (since with the expected name GDB work seamlessly).
