[PATCH 0/2] [MIPS] Emit .note.GNU-stack for linux targets.

[Dragan Mladjenovic]

From: "Dragan Mladjenovic" <dmladjenovic@wavecomp.com>

Greetings,

These patches enable emitting .note.GNU-stack by default on mips linux targets.
First one enables it unconditionally for soft-float builds while the second one
enables it for hard-float build if gcc is configured against the future version
of glibc that should enable safe usage of PT_GNU_STACK [1].
