Option 4: use the --enable-compat option of pthsem, which was precisely
designed to offer compatibility with pth, by installing pth.h and
pth-config. The only issue was the version check in gnupg2 not
accepting the not-completely-compatible behavior of pth-config from
pthsem. A one byte patch in gnupg2 solved the problem.

Therefore, this patch (gnupg2) has been applied, after changing the
dependency from pth to pthsem, removing the !uclibc dependency, and
fixing minor formatting issues in the .mk file.

Thanks!

Thomas
