I've never looked at how the authors of libgomp wrote the
build glue nor have I tried to decipher why one would specifically
suppress OpenMP with the -fno-openmp option yet still try to
link to its runtime library. It does appear that libgomp/configure
looks to see if -pthread (or -lpthread) is required, but then it
may not use that result in actually building libgomp.so.1
