--- Comment #1 from Kyle Farnsworth <kyle at farnsworthtech dot com> ---
I encountered this same issue. When I added the -print-sysroot option to see
what gcc was thinking was the sysroot setting it revealed this:
WITH -m4 option:
$ sh4-oe-linux-gcc -ml -m4 --sysroot=sysroots/sh775x-oe-linux -print-sysroot
sysroots/sh775x-oe-linux/m4
WITHOUT -m4 option:
$ sh4-oe-linux-gcc -ml --sysroot=sysroots/sh775x-oe-linux -print-sysroot
sysroots/sh775x-oe-linux
It appears some arguments are getting mangled and somehow the m4 option is
concatinated to the end of the sysroot.
My workaround was to add symlink sysroots/sh775x-oe-linux/m4 to point to "./".
$ sh4-oe-linux-gcc --version
sh4-oe-linux-gcc (GCC) 4.7.2

Kaz, maybe you have an idea whether/how this could be improved?

I'm also using symbolic links for those issues and have no good
idea for multilibs handling itself. Clearly a true fix will be
welcome, though our handling/setting for SH multilibs looks a bit
too complicated already.

With multilibs enabled this is usually the correct behaviour, but I wouldn't
have expected this with --disable-multilib.
