Remove m1 from multilibs for GCC11 on SH arch.

Browse Source 
GCC11 somehow has different set of multilibs on SH arch than what GCC10 had.
In particular:

$ gcc10 -print-multi-lib | sed -r -e 's/@/ -/g;'
.;
mb; -mb
m2; -m2
m2e; -m2e
m4; -m4
m4-single; -m4-single
m4-single-only; -m4-single-only
mb/m2; -mb -m2
mb/m2e; -mb -m2e
mb/m4; -mb -m4
mb/m4-single; -mb -m4-single
mb/m4-single-only; -mb -m4-single-only
mb/m2a; -mb -m2a
mb/m2a-single; -mb -m2a-single

$ gcc11 -print-multi-lib | sed -r -e 's/@/ -/g;'
.;
mb; -mb
m2; -m2
m2e; -m2e
m4; -m4
m4-single; -m4-single
m4-single-only; -m4-single-only
mb/m1; -mb -m1
mb/m2; -mb -m2
mb/m2e; -mb -m2e
mb/m4; -mb -m4
mb/m4-single; -mb -m4-single
mb/m4-single-only; -mb -m4-single-only
mb/m2a; -mb -m2a
mb/m2a-single; -mb -m2a-single

mb/m1 fails to build libgcc as libgcc uses opcodes that were not
available in SH-1: libgcc/config/sh/lib1funcs.S uses 'bt/s' and 'dt'
instructions that, according to https://antime.kapsi.fi/sega/files/h12p0.pdf become available in the SH-2 only.

So I removed mb/m1 from the multilibs fog GCC11 and SH arch.
Another option would be to try not to build libgcc for this combination
of the gcc version and archichecture, but I thought this fix would be
more robust.
