a semi-quick scan shows that you're missing hidden symbol aliases
for example, in your chmod change, you call fchmodat (which is fine), but
there's no addition of libc_hidden_{proto,def} for fchmodat.
to check for this, you can run `readelf -r` on the libc.so file and look at all
the function relocs. the only ones in that list you should see are malloc
related (malloc/free/calloc/etc...). if you see other symbols, they're most
likely missing the libc_hidden stuff.
