>Description:
libgpgme.so gets linked to libpthread erroneously:

/usr/pkg/lib/libgpgme.so:
        -lpthread.0 => /usr/lib/libpthread.so.0      <--- wrong
        -lrfuncs.1 => /usr/pkg/lib/librfuncs.so.1
        -lintl.0 => /usr/lib/libintl.so.0
        -lgpg-error.0 => /usr/pkg/lib/libgpg-error.so.0

/usr/pkg/lib/libgpgme-pthread.so:
        -lpthread.0 => /usr/lib/libpthread.so.0      <--- ok
        -lrfuncs.1 => /usr/pkg/lib/librfuncs.so.1
        -lintl.0 => /usr/lib/libintl.so.0
        -lgpg-error.0 => /usr/pkg/lib/libgpg-error.so.0

This causes the problem described in PR#30414.

A vanilla "./configure && make" out of pkgsrc under NetBSD-current:

./libgpgme-pthread.so:
        -lpthread.0 => /usr/lib/libpthread.so.0
        -lintl.0 => /usr/lib/libintl.so.0
        -lgpg-error.0 => /usr/pkg/lib/libgpg-error.so.0

./libgpgme.so:
        -lintl.0 => /usr/lib/libintl.so.0
        -lgpg-error.0 => /usr/pkg/lib/libgpg-error.so.0

In private emails, I've discussed this issue with Nathan Williams and
he noticed that if libgpgme.so isn't compiled with pthread support,
pthread_mutex_* calls get expanded with to no-ops, which doesn't trigger
the assertion in PR#30414.

I will notice gpgme folks to this problem. Meanwhile we should probably
make libgpgme.so not to link with libpthread.so.
