Did you follow the recommendations at https://gcc.gnu.org/install/specific.html#ix86-x-solaris210 ?
"It is recommended that you configure GCC to use the GNU assembler"

It is better to compile a dummy program with g++ -v, it ensures that you get version info about the assembler that g++ actually calls.
We would like to ask GCC to use NASM instead of 'as'.
I don't think nasm is supported, try gas instead.
Is there a way to tell GCC to use a different assembler?
If the compiler is really different (not just a newer version with compatible options), you need to recompile gcc.
