libgpg-error installs ${CHOST}-gpg-error-config.

Now libgcrypt (and possibly other tools) are using AC_PATH_TOOL to find
it. If we have proper CHOSTs, they find the right gpg-error-config
and we don't have to put any more effort into that. Then libgcrypt
installs ${CHOST}-libgcrypt-config.

Now other tools are using AC_PATH_TOOL to find proper libgcrypt-config.
If we have proper CHOSTs, it just works and we don't have to put any
more effort into that.

Same goes for LLVM & Mesa.

If we play by the rules nicely, all pieces fit together nicely and we
don't have to worry. If we don't, we ask the developers to spit Gentoo-
specific hackery all over the place.
