[Bug c++/15466] New: libstd++ build error for sh-hms

["adx at swissonline dot ch" <gcc-bugzilla at gcc dot gnu dot org>]

The build failes with the following message:

configure: WARNING: No native atomic operations are provided for this platform.
configure: WARNING: They cannot be faked when thread support is disabled.
configure: WARNING: Thread-safety of certain classes is not guaranteed.
configure: error: No support for this host/target combination.
make: *** [configure-target-libstdc++-v3] Error 1

The overall configure was invoked with the following command line:
../configure --prefix=/usr/local/gcc3-sh --target=sh-hms -v

The first lines in sh-hms/libstdc++-v3/config.log are:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by package-unused configure version-unused, which was
generated by GNU Autoconf 2.57.  Invocation command line was
