kernel: add workaround to keep kernelconfigs stable
With linux-4.19 and gcc-8.x oldconfig will prompt for extra options that
are not available with e.g. gcc-7.x. This causes problems when a BSP is
built with different host compilers.
Add a workaround to optionally disable these extra options by forcing the
compiler check to fail.
