Well known problem. Solaris/x86 (all versions including 2.10) has a 
broken assembler (if not "broken" at least not 100.00% compatible to GNU)

So one must use the GNU assembler in certain cases.

To make it all work, I also had to build a custom gcc in my old x86 days 
which
was configured "--with-gnu-as" (and perhaps also "--with-gnu-ld", I
don't recall). The procedure is described in the gcc sources.
Today one may just use "/usr/sfw/bin/gcc", NOT 
"/opt/csw/gcc[2|3|4]/bin/gcc" !

Here you see the difference:
