kbuild: Remove compilation tool command line validation

Browse source 
To support multiple versions of the compilation tools GCC etal the
original Kbuild would execute the tool to ascertain if the argument
being added to command line was compatible with the version of the
tool installed on the system.  This causes significant overhead and is
not required since we specify the minimum version of the tools
required for the build.
