Thanks Orson.  Not to make a mountain out of molehill, one of our supported platforms is
desktop "linux".

Desktop Linux does not imply x86 or x86_64.

It implies any desktop linux.  This includes multiple processor architectures, not the
least of which is ARM.  Some folks have already had KiCad running on ARM.  ARM will be a
player for the indefinite future of linux.  ARM is supported in boost::context.
boost::context does not support mingw's binutils.

It was the choice to use co-routines that comes at this cost.  It is not a high cost, but
not negligible.

Probably the path of least resistance, from here, is to add the binutils patch to our
boost ExternalProject_Add() patch set, re-enable boost::context, and then keep submitting
these patches upstream.

I don't think we've done that even for the current boost patch.  We can ping the patch
requests from time to time, offer them under different submitter names, make noise.
