Don't build abi_check for crosses

[Daniel Jacobowitz]

This is the 3.3 version of the patch.  3.4 the test is negated and against
GLIBCXX_IS_NATIVE:
if test x"$GLIBCPP_IS_NATIVE" = xfalse || test x$enable_symvers = xno; then

This is necessary because automake can't build abi_check for the host. 
Right now it's listed as a target program, and will be linked to the newly
built libstdc++; if $build != $host or --with-cross-host, we won't be able
to run it even if we were able to build it.  Ben, CC'd you because you
removed the comment saying to build it native only; was there a reason?

OK?
