We probably don't understand each other. CFLAGS changes compiler flags
globally, i.e. for gcc binary, for libgcc targets, libstdc++ targets etc. So
when libgcc should be build for 5475 and we set CFLAGS with m68020-60,
there's a clash because commandline looks like:

m68k-atari-mint-gcc  -mcpu=5475 -o conftest -g -m68020-60 -O2
-fomit-frame-pointer    conftest.c

(confirmed by test) so I was asking for some solution where the right things
get CFLAGS with m68020-60 and the multilib things get the original CFLAGS
and I thought --with-arch=XYZ could help but it's not supported.
