MIPS: Add buildtime option to set msa default
Add buildtime option to decide whether will compiler build with `-mmsa` option default. gcc/ChangeLog: * config.gcc: add -with-{no-}msa build option. * config/mips/mips.h: Likewise. * doc/install.texi: Likewise. Signed-off-by: Junxian Zhu <zhujunxian@oss.cipunited.com>
