glibc clone for linux-mips

[Ralf Baechle]

The MIPS jalr assembler instruction will not restore the $gp register so
if the function called by clone should return the following call to exit
might result in a crash.  Below patch against glibc 2.2 and trunc will
fix the problem.  Please apply,

  Ralf

	* sysdeps/unix/sysv/linux/mips/clone.S (__thread_start): Use jal
	instead of jalr to invoke subroutine so restoring the $gp register
	will work properly.
