Warner Losh e35448a901 powerpc: Drop old workaround for old gcc
Very old versions of gcc defined _BIG_ENDIAN and _LITTLE_ENDIAN. So to
work around that, we undefined them here. However, that causes problems
for programs that do:

(and many other variations on that theme). Since this often is the
result of weirdly nested includes in the ports world that are hard to
unwind, drop this workaround to help more ports build out of the box.
If there's still an issue here (and my testing hasn't shown it), we'll
fix the issue in a brand-new way once I have a reproducer.

This fixes the mesa-devel build, and others
