Subject: sim: ppc: enable use of gnulib
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a13ab747e7abc67fca3568195bf943708261a39e;p=binutils-gdb.git

sim: ppc: enable use of gnulib

All other sim arches are using this now, so finish up the logic in
the ppc arch to enable gnulib usage here too.
