[Buildroot] [PATCH 0/2] Update crostool-NG backend

[Yann E. MORIN]

Hello All!

This short patch series updates the crosstool-NG backend in two ways:
 - patch 2 is the simple one, and  updates to 1.12.1, which has a few
   fixes since 1.12.0

 - patch 1 is in itself quite simple, but the reasoning behind it is a
   bit more complex, and gave me a headache for a few evenings before I
   could pin-point the issue. More explanation in the patch description.

   Of course, this would require much more love to properly fix, but not
   that close to a release. Hopefully, we can use the dev day in Prague
   to disguss the issue.

   [PATCH 1/2] toolchain/crosstool-NG: fix bundled config files
   [PATCH 2/2] package/crosstool-NG: update version to 1.12.1

Regards,
Yann E. MORIN.
