OK.

I have no strong preference either way. But I would like them to be
installed once. In light of the fact that the 'GNUmakefile' isn't really
supported, I am more than willing to just use David's supported
'Makefile' for everything.

Currently I am running core/make/configure twice. To make sure I
understand this correctly... The first time is just to get

${PREFIX}/System/Library/Makefiles/GNUstep.sh

generated so that I can use GNUmakefile to build libobjc2. Once that is
built running it again detects the in-tree libobjc2 libraries and uses them?

If I move to using 'Makefile' instead of GNUmakefile to build it then do
I only need to run core/make/configure once after I build libobjc2 and
pass the path of the library to configure?
