commit 0542632f435d2f0657c3849155fe12d8ab0ce8a4

    testsuite/systemtap.exelib allow any libc function to occur as start_func.
    
    On some arches some libc startup function don't have a starting _.
    e.g. on powerpc there is generic_start_main().

    Disable uregs recovery through kernel dwarf unwinder for powerpc.
    
    Sadly powerpc does support the dwarf unwinder, but doesn't have enough
    CFI in the kernel to recover fully to user space.

    Don't try to do any lookup when addr is zero in _stp_kallsyms_lookup().
