[Bug c/44165] New: 5/15/2010 snapshot build failure on hppa Linux

[michael dot a dot richmond at nasa dot gov]

When I attempt to compile the snapshot of 5/15/2010 on an HPPA workstation
under Debian Linux 5.0 I get the following messages:

checking whether the C compiler works... configure: error: in
`/home/mrichmon/gcc-4.6-20100515/g95/hppa1.1-unknown-linux-gnu/libgomp':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.

I have also seen this error.

It's a bit of a puzzle.  A segfault occurs in the startup of
the a.out file run by configure.  A null constructor address
is loaded from the constructor table causing the fault.

        * cgraph.h (struct varpool_node): Add aux.
        * varasm.c (find_decl_and_mark_needed): Force output of varpool nodes.
        * varpool.c (varpool_remove_node): Do not remove initializer.
        (varpool_reset_queue): Export.
        (varpool_finalize_decl): Volatile vars are forced to be output.
        * lto-symtab.c (lto_varpool_replace_node): Clear out initializer of
        replaced decl.
        * ipa.c (enqueue_cgraph_node, enqueue_varpool_node,
