At some point the libstdc++ library configure script added a test for
cross compiling, if so it disables all configure time compiler-link
tests on the premise that the tool chain cannot link.
In the crosstool-ng case, with at least glibc/eglibc, the libstdc++
build is done at the very end after a full libc is installed and all
the start files are valid. The compiler can link, so take the test out
of the libstdc++ configure.
Two reasons
1) The libstdc++ configure has a hackish work around path for the no link case,
we don't want to use it unless *absolutely* necessary
2) Some systems will hit this error:
checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
Which is due to the usage of libtool triggering a link test.

Most of this patch is just a rebuild of the autoconf. My patches are
available on github: https://github.com/jgunthorpe/crosstool-ng
I put this in the 4.6.3 directory because that is what I am using, but
it looks like it is needed for all of 4.6 and 4.7, there are many
reports of build failures due to this problem on the internet, I
assume it is triggered by a newer libtool in Oneiric or some such?
It would be great if this could be fixed in upstream GCC, maybe a
better approach would be to directly check if the compiler can link
and only then enable the GCC_NO_EXECUTABLES function, rather than
making assumptions based on cross compiling??
