[Buildroot] [PATCH 1/1] Makefile: enforce toolchainfile.cmake consistency with the actual toolchain

[Samuel MARTIN]

This patch makes the toolchainfile.cmake generated after the toolchain
generation or import and checks (depending on the backend used).

This ensures the correctness and consistency between the actual
toolchain and the toolchainfile.cmake file describing it.

This also makes the toolchainfile.cmake generated when building the
target 'cross'.
