Hi,

I've identified this commit in a git bisect that is related to
something strange: Before this commit, an Arch linux-based machine I
have gives this error when building:

/usr/bin/ld: port/pg_sema.o: undefined reference to symbol
'sem_post@@GLIBC_2.2.5'
/usr/bin/ld: /usr/lib/libpthread.so.0: error adding symbols: DSO
missing from command line
collect2: error: ld returned 1 exit status

I figured there must be something broken on my end, but wanted to
mention it here in case something bigger is going on.
