loader/powerpc: Share ldscript
Share ldscript between the different ppc versions. There's two different scripts since we build 32-bit binaries for all types of powerpc, but have little endian and big endian variations that are different by only two lines. Set the output format and include the rest. Move to foo.ldscript as well.
