[Message part 3 (text/plain, inline)]

* m4/guix.m4 (GUIX_ASSERT_SUPPORTED_SYSTEM): Don't error if building on
an unsupported system.
* doc/guix.texi (GNU Distribution): Relabel mips64el-linux as
unsupported.
---

As we discussed previously with the powerpc-linux patches, I've gotten
around to changing the m4 error to a warning. Also, I didn't change
i586-gnu to say unsupported next to it in GNU Distribution in the
manual, although I suppose the other option would be to add i586-gnu to
supported in m4/guix.m4.
