I see.  Thanks for your teaching.  I realized that there are more detail
than I had expected.

Today, I updated the change [0] to allow CC as one of clang.  I'm going
to push this change, soon.

My intention is to show our support making gpg-error-config script
architecture independent on multiarch environment, to avoid having many
<triplet>-gpg-error-config scripts.  I wish we will have co-installable
libgpg-error-dev:amd64 and libgpg-error-dev:i386 on Debian, and we won't
need any change for gpg-error.m4 (and updating it in several packages).


Now, I think that more changes (Debian specific) are better to be left
to Debian Maintainer of libgpg-error.

FYI, upstream discussion is here [1].
