Unfortunately that won't work in general; the comment for mod-test.so 
says "In the compilation command, we can't use any object or archive 
file as source because those are not compiled with -fPIC" but as things 
stood mod-test.so was being linked with libgnu.a.

Anyway, mod-test.so should be decoupled from Emacs as much as possible - 
that's the whole point of modules after all - so the mod-test.so rule 
shouldn't make assumptions about how Emacs internals use Gnulib. I 
installed the attached patches to lessen the coupling between 
mod-test.so and Emacs internals and I hope this fixes the problem. It 
may need to be adjusted a tad for platforms that lack 
nanosleep/clock_gettime/libgmp whatever, but the basic idea should work 
on these platforms with only minor twiddling.

Even with these patches, mod-test.so uses "config.h"; but at least it 
doesn't use Gnulib code.
