[Buildroot] [PATCH] toolchain: adjust version check to allow for single numbers

[Yann E. MORIN]

Norbert, All,

On 2020-06-11 01:53 +0200, Norbert Lange spake thusly:
> A gcc compiler, which was configured with
> --with-gcc-major-version-only, will only return a single
> number. (debian does this for example).
> 
> A simple modification allows the check to work with both
> single numbers (eg. '9') and full versions (eg. '9.2.1').
> 
> Signed-off-by: Norbert Lange <nolange79 at gmail.com>

Applied to master, thanks.

Regards,
Yann E. MORIN.
