Signal stack support for MIPS ____longjmp_chk.
* sysdeps/mips/____longjmp_chk.c: Remove. Replaced by....
* sysdeps/unix/sysv/linux/mips/____longjmp_chk.c: This. New file.
* sysdeps/mips/__longjmp.c (__longjmp): Use explicit register
variable for env. Use expansion of CHECK_SP macro for check.
* sysdeps/mips/mips64/__longjmp.c (__Longjmp): Likewise.
