Make gcc.dg/fshort-wchar.c use -Wl,--no-wchar-size-warning on ARM EABI

Just as some testcases use -Wl,--no-enum-size-warning for
arm*-*-linux*eabi to avoid linker warnings about different enum sizes
in input files, so the testcase gcc.dg/fshort-wchar.c triggers a
linker complaint about different wchar_t sizes.  I've added a
--no-wchar-size-warning option to binutils; OK to commit this patch to
make the test use it?  (It already fails for this target in the
absence of the option, so I don't think failing with a different error
if you use binutils predating the option is a problem.)
