[Buildroot] [Bug 7956] glibc 2.20 and 2.21 fail to build for sh64-buildroot-linux-gnu

Do you actually use/need sh64 support? We're thinking of removing/deprecating
it.

Well, I don't need it personally (at the moment), but we're trying to
cross-compile our software (sigrok, open-source test&measurement project, see
www.sigrok.org) for as many platforms as possible in order to catch any
portability issues. We're using buildroot-built toolchains and sysroots for
that since it's quite convenient.

See e.g.
http://sigrok.org/jenkins/job/libserialport/
http://sigrok.org/jenkins/job/libsigrok/

I don't know if we currently have users for sh64 or not, but that should not be
relevant for this issue really.

I guess the question is whether mainline glibc supports sh64 at all or not. The
text "configure: error: The sh64 is not supported." suggests the latter. But I
didn't check whether that's actually true or an incorrect error is emitted
(and/or whether sh64 support is planned to be added to glibc).

Note: I haven't tried the eglibc option for sh64 in buildroot, maybe that one
does have support (?)

We've now marked sh64 as deprecated in Buildroot. According to the commit log:

    sh64: deprecate support for this dead architecture

    As discussed on the mailinglist, this should be deprecated
    before removal.
