Hello,

the new RTL optimization introduced in [1] breaks the gcc-14 build on m68k.

As discovered by the Gentoo m68k maintainers, building gcc-14 with the option
-fno-fold-mem-offsets to disable this new optimization fixes this problem.

The option does not seem to be needed on gcc-15 which builds fine in experimental [2].

I have used the following patch against the gcc-14 package to pass the option
during build which works for me:

   CFLAGS_FRAME_POINTER = -fno-omit-frame-pointer

The gcc maintainer will certainly know better whether all of these are
needed to fix the build and consequently avoid other packages from being
miscompiled or failing to build.

Thanks,
Adrian
