"-mshort" is still used with m68k gcc toolchain(s) that don't break it.  Not to
build Linux binaries, but to cross-compile things where size matters.  

It would be nice to be able to use (pre-built Debian) Linux m68k gcc to do such
cross-compilation.

Looking at https://gcc.gnu.org/git/?p=gcc.git;a=tree;f=gcc/config/m68k;hb=HEAD

"linux.h" and "netbsd-elf.h" headers use int & unsigned int for PTRDIFF &
SIZE_T, which produces broken code with -mshort, whereas "openbsd.h" and
"m68kemb.h" use "long int" & "long unsigned int" which work fine with and
without -mshort.

(I'm not sure whether I should be surprised that netbsd and openbsd work
differently. :-))
