No, when you use -lpthread (and there are both a static and a shared
library available) then the binary will be linked against the shared
library. If you really want to link against a static lib then you have
to refer to it using the full path (and without the '-l' flag), so
you'll get something like:

x86_64-w64-mingw32-gfortran -o omp omp.F -static
-fopenmp /usr/x86_64-w64-mingw32/sys-root/mingw-lib/libpthreadGC2.a

However, there's another catch here. There is no
mingw32/64-pthreads-static package available at the moment..so the above
command won't work. If you want to run your application you need to
bundle the pthread dll for now.
