Bootstrap failed in following configuration.
configure --target=sh-unknown-linux --enable-languages=c --disable-libatomic --disable-threads --disable-shared --disable-libssp --disable-libquadmath --disable-libgomp
xgcc: error: SH2a does not support little-endian
So add build exception for SH2A.

This disables SH2A completely? AFAIK SH2A big-endian Linux is a valid
configuration. It should be 'm2a/ml' only, as in t-sh. Although all of
that will probably not work if --with-endian=little,big or
--with-endian=little is specified as configure option.
Cheers,
Oleg

How about a bit modified patch below?

It works fine.
Thanks.

Thanks for checking. I've committed it on trunk as revision 221287.

I think the same should be done in t-sh and in t-linux we could add the
SH1 little endian exception, too ... just in case (see attached patch).
I'm not sure whether TM_MULTILIB_EXCEPTIONS_CONFIG is needed in t-linux
or not. Moreover, I don't understand why t-linux doesn't pick up
MULTILIB_EXCEPTIONS from t-sh.... any ideas?
Cheers,
Oleg

Your patch looks OK, though I guess that the current t-linux would
be enough. sh-linux compiler requires libc implementation and some
combinations aren't practical for t-linux in the first place.
