[Buildroot] [PATCH] toolchain/crosstool-NG: only use the un-tainted Buildroot version sting

[Yann E. MORIN]

The 'full' Buildroot version string contains the git cset hash, so will
change for each commit in the current tree.

As Przemyslaw points out, this will cause the crosstool-NG backend to
rebuild the toolchain, as the 'full' Buildroot version is included in
the crosstool-NG config (to further push down to the components version
string).

Using the 'full' Buildroot version string is arguably useful, so switch
to using the 'simple' Buildroot version string instead.
