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 -- Steve
