freebsd/libexec/rtld-elf/Makefile
Nathan Whitehorn 27bd4146a1 RTLD support for powerpc64. A few small modifications to the Makefile
and symbol map are required to support various consequences of the dot
symbol scheme:

- Symbols beginning with a dot are reserved, so start private symbols with
  an underscore.
- In order to set RTLD breakpoints, gdb must be able to locate the text
  entry point, not the data section function descriptor, so add
  .r_debug_state to the symbol map on powerpc64.
