Fix 'illegal option -xassembler-with-cpp' error (Oracle SunCC)

* Makefile.am (ASM_CPP_OPTIONS): Move comment to configure.ac.
* Makefile.am (COMPILER_XLC): Rename to ASM_WITH_CPP_UNSUPPORTED.
* configure.ac (COMPILER_XLC): Likewise.
* configure.ac (compiler_suncc): New variable (set to "yes" if Solaris
Sun C compiler).
* configure.ac (ASM_WITH_CPP_UNSUPPORTED): Define not only for
compiler_xlc but also for compiler_suncc.
