[Buildroot] [PATCH 1/2] ruby: don't try to use gmp on the host

[Thomas Petazzoni]

When building host-ruby, if gmp seems to be available (for example
when host-gmp is built as a dependency of building the toolchain),
Ruby tries to use it. Unfortunately, it fails to use it because there
is no static version of host-gmp that is built and installed.

Since we anyway don't care much about gmp support in host-ruby, simply
disable it.

This issue was introduced since the bump to Ruby 2.1.0, and this
commit fixes:
