* configure.ac (HAVE_AS_IX86_DIFF_SECT_DELTA): New test to determine
whether the assembler supports taking the difference of symbols in
different sections. On x86/Solaris, GAS does but Solaris as doesn't.
* configure: Regenerate.
* config.in: Regenerate.
* config/i386/sol2-10.h (JUMP_TABLES_IN_TEXT_SECTION): Define if
the assembler doesn't support taking the difference of symbols in
different sections, i.e. we're using the native solaris assembler.
