using <= instead of <, slof used to loop over the phdrs. It overruns by
1 and so on little endian it swizzles the first 32 bytes of .text. Work
around this by adding 32 bytes of padding after the headers. We should
fix this in slof, but it's in the just released QEMU 10.2, so we have to
pad things here for now.
Now powerpc64le + qemu works.
MFC After: 3 days (maybe EN too)

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.
