>Description:
	A few days ago, we added USE_GCC=yes as another (and now 
	preferred form of USE_GCC).

	The patch below is a strawman of getting this supported by
	portlint.  I went ahead and made USE_GCC=any and USE_GCC=yes
	a distinct check, so that we can become stricter in filtering
	unsupported options of USE_GCC later on that someone might use.
