    Add -mrelax-relocations= to x86 assembler

    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.
