0.8.6.14:
	Ouch.  That was hard work.
	... contrib fix primarily for SunOS but also I think for Darwin;
		at least, if it was working it was only by accident.
	... uname -m never returns either "solaris" or "darwin", so that
		code was wrong to start with;
	... change the protocol so that we do EXTRA_CFLAGS rather than
		a complete override; now we don't need the solaris or
		darwin clauses in asdf-module.mk that weren't being used
		anyway;
	... delete more stuff in make-target-contrib.sh so that we can
		actually see the effect of these changes rather than
		blindly reusing an old alien.so (which explains why I
		hadn't noticed this before, *sigh*; I ran a completely
		clean build on Solaris for the first time in months
		yesterday)
	... now sb-bsd-sockets and dependents work again.  I hope I haven't
		broken x86-64 in the process.
