It looks like GCC thinks it's talking to the GNU assembler when in fact it's using the HP bundled assembler. IIRC the bundled assembler can't emit debugging information so you're well advised to get the GNU assembler from the binutils package. Once you have that GCC should just work. Alternatively, you can rebuild GCC yourself from source to expect the bundled assembler but it takes a bit of manual intervention - the bundled assembler embeds timestamps, for example, so the usual GCC bootstrap trips comparing stages 2 and 3 when the object code might actually match. And chances are the odd ISO-ism has crept into the source so it might not build using HP bundled C straight out of the box. Good luck, Rup.
