How about a change like this?

    https://dev.gnupg.org/D467

At configure time, if it detects libdir for multiarch, it lets
gpg-error-config script architecture independent to dynamically define
PKG_CONFIG_LIBDIR (by CC or gcc -dumpmachine).

With this, we don't need to have <triplet>-gpg-error-config.
