Fixes to allow libgcc to build for the sh64-linux target
I am no SH expert, so this patch may well be wrong. But it does allow libgcc
to built (for all supported multilibs) for the sh64-linux target.
There seem to be three problems:
1. As reported in this PR, the sdivsi3 function is being built for the
L_div_table target when it clearly uses instructions that are not supported by
the target SH variant. I have assumed that this is a mistake and so stopped
the function from being built for the m5-compact multilib.
2. The udiv_qrnnd_16 function is not being built. It is built for non-Linux
Sh targets, so I have assumed that it is an oversight and added it to the list
of functions to build.
3. The m5-media64 and m5-media64-nofpu multilibs need the linker to support a
shlefl64_linux emulation. The linker does not do this, so I have suppressed
all multilibs based on these options.

The first hunk of the patch that adds:
MULTILIB_EXCEPTIONS = *m5-64media* *m5-64media-nofpu*
to gcc/config/sh/t-linux causes the sh-linux-gnu build to fail. Commenting out
this line allows both sh- and sh64-linux-gnu to build.

I guess there is a conflict with the "!" values in
--with-multilib-list=m1,m2,m2e,m4,m4-single,m4-single-only,m2a,m2a-single,!m2a,!m2a-single
passed to the sh-linux compiler

I think this issue was fixed by r218190:

* config/sh/lib1funcs.S: Check value of __SHMEDIA__ instead of checking
whether it's defined.

Segher, was the error in the original description here the same you were
hitting when building sh64 linux?
