commit 0c096dcf14df1ed6ce869015ca623d8fabf1f0ef
Author: Joseph Myers <>
Date:   Tue Nov 13 01:55:15 2018 +0000

    Fix mips build with GCC 9.
    This patch fixes the build for MIPS (o32) with GCC 9 by stopping MIPS
    __longjmp from using strong_alias, instead defining the alias
    manually, so that the intended effect of not copying the nomips16
    attribute is achieved, as explained in the included comment.
    Tested with compilers build for mips64-linux-gnu
    (which includes glibc builds for all three ABIs).
    	* sysdeps/mips/__longjmp.c (__longjmp): Define alias manually with
    	alias attribute, not with strong_alias.
