Use just-built gcc for windres
When building cygwin in a combined tree with binutils,
the just-built windres cannot find the just-buit gcc automatically.
Parse the CC env variable to use the correct compiler, rather then
falling back to the build-system's gcc which does not define the proper
preprocessor macros.
