[gdb] [rs6000] Add ppc64_linux_gcc_target_options method.

Add a method to set the gcc target options for the ppc64 targets.
This change sets an empty value, which allows the gcc
default values (-mcmodel=medium) be used, instead of -mcmodel=large
which is set by the default_gcc_target_options hook.
