>Description:
The graphics/MesaLib does not have any dependencies on pthreads, but
the linking of libGL.so does add -lpthread.  This makes libtool
add --lpthread in .la file, with the result that all packages
linking to libGL.so need to add an explicit dependency on pthread,
even if they don't use threads.

I think the -lpthread should be removed -- no pthreads .h files
are available during the build, so the package cannot be using
any thread functionality?  Otherwise a proper pthread dependency
should be added to the package (and its buildlink3.mk)
