I agree with you.

I have patches to do that for years, perhaps we can merge our both
solutions to have something working:

linux-user: define default cpu model in configure instead of
linux-user/main.c
https://github.com/vivier/qemu-m68k/commit/1488df8c9fa3a5b099bbc4f41c077a6c69305cc2

linux-user: specify the cpu model during configure
https://github.com/vivier/qemu-m68k/commit/496f804fd97d5f0ef26da1090e1d95ad15bcc50e

The part missing in my series is to rename the qemu binaries with the
suffix of the default CPU.

Thanks,
Laurent
