That's my point: that late in the cycle, I don't want to touch too
many things around the toolchain wrapper. So adding one more CFLAGS or
LDFLAGS specific to m68k is OK (worst thing is a regression on m68k,
which probably isn't very widely used). But a change that touches the
toolchain wrapper, and can potentially break major architectures, I'm
not a big fan.

If nobody provides the bigger patch, I think I'm going to live with the
m68k autobuilder failures until the release, and merge afterwards.
