Gmp test failure on armhf

[Andreas Enge]

Hello,

I installed guix via the binary tarball on my novena, then built a toolchain
with guix and rebuilt the guix from git with it. So far, I am still using the
binary tarball daemon.

When running
   ./pre-inst-env guix build hello
the build fails with a test failure in gmp.
Before investigating further, I wonder if anybody else has had a similar
problem? Or am I the only one using a recent git checkout of guix after
the switch to a newer gcc version?
