[PATCH 3/3, not 3/4] musl: Move __SIGRTMIN


Hi.

Sorry, I miscounted, this patch series has 3, not 4 as mentioned here:
https://sourceware.org/ml/gdb-patches/2015-10/msg00495.html

This patch moves __SIGRTMIN out of gdbserver so gdb can use it too.

With this series gdb builds and runs on musl.
Testsuite results are reasonable for now.

	* gdbserver/linux-low.c (__SIGRTMIN): Move to ...
	* nat/linux-nat.h (__SIGRTMIN): ... here.
