RE: [PATCH] mips: Do not use jal to reach __libc_start_main

In short, the failing test program (reported in #17601) has been tested
in the following combinations (given to gcc):

1. -EL
2. -EL -fPIC
3. -EL -fPIC -pie
4. -EL -mabi=32 -mips16
5. -EL -mabi=32 -mips16 -fPIC
6. -EL -mabi=32 -mips16 -fPIC -pie

To execute it correctly for options 1, 2, 4 and 5, additional change
(described in the bug tracker) was added in gcc/config/mips/mips.h.

Further, a subset (1500 tests) from DejaGnu GCC test suite has been
executed and has shown no regressions.

Could you detail how this patch has been tested?  (And provide a ChangeLog 
entry for it.)
