This problem block mod-gnutls from building on arm64, and is one of the problems
blocking mod-gnutls from entering testing. This is a problem for
freedombox-setup, which need mod-gnutls.

I suggest a different approach, where the macro is rewritten to first check if
the build is already 64bit, and if not, try with -m64 using this patch:

Note, the patch did not change the indentation of unrelated code. This should
be done if the change is merged upstream, for consistent indentation.
I didn't change the indenation to make the patch easier to read.
