Thank you for the report.

I think that this is an issue of libc/libpthread usage.

In fact, newer GNU C library has similar issue, as pthreads
implementation is now integraged into libc (no need for -lpthread).

In GnuPG libraries, we handled this issue in libgpg-error.

Because GPGME uses libgpg-error, I change tests/Makefile.am to fix.

Please test if it works for your case.
