you can also use Vincents cygwin/ubuntu cross-tools build scripts as a
source of info, as I have to create m68020-60 builds of ALL packages
available from:
http://vincent.riviere.free.fr/soft/m68k-atari-mint/archives/mint/

eg. how to build multiple libraries with different settings, manual move
http://vincent.riviere.free.fr/soft/m68k-atari-mint/archives/ncurses-5.9-bin-cygwin-howto.txt
note: according to the last 3 lines only the m68000 build is packaged,
but you get the idea.
"m5475/lib/*" goes (on SpareMiNT) in "/usr/lib/m5475/*"
"m68020-60/lib/*" goes (on SpareMiNT) in "/usr/lib/m68020-60/*"
"m68000/lib/*" goes (on SpareMiNT) in "/usr/lib/*"

eg. how to build multiple libraries with different settings, and where
to install them
http://vincent.riviere.free.fr/debian/dists/oneiric/contrib/source/cflib-m68k-atari-mint_0.21.0-CVS-20120227-1.tar.gz
look in "debian/rules", and in "Makefile" in the enclosed source
archive (normal, normal020, normalv4e)
