The x86 relax relocations introduced in binutils 2.26 aren't supported by linker on Solaris older than Solaris 12. To use x86 assembler with older Solaris linker, this patch adds 1. A command line option -mrelax-relocations= to x86 assembler to control whether to generate relax relocations. 2. A configure option --enable-x86-relax-relocations to decide whether x86 assembler should generate relax relocations by default. It is defaulted to yes, except for x86 Solaris targets older than Solaris 12. gas/ PR gas/19520 * NEWS: Mention new command line option -mrelax-relocations and new configure option --enable-x86-relax-relocations for x86 target. * config.in: Regenerated. * configure.ac: Add --enable-x86-relax-relocations.
