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.
