The problem is, I can't seem to be able to get the u-boot build to invoke it... it seems like "swig" is being invoked by some python code itself, perhaps deep in the bowels of some library that's installed with python37.

swig2/Makefile mentions that swig2.0 is a standard name for swig, and
a possible workaround for autotools based build systems:

# Solution: Use --program-suffix=2.0, not --program-suffix=2

So perhaps something like that might work.

Otherwise, perhaps something like this will help:

	${LN} -s ${PREFIX}/bin/swig3.0 ${BUILDLINK_DIR}/bin/swig
