[pushed] Darwin, crts: Fix a build warning.

[Iain Sandoe]

We have a shim crt for Darwin10 that implements functionality
missing in libSystem. Provide this with a prototype to silence the
warning about this.

Tested on x86_64-darwin, pushed to master, thanks,
Iain

	* config/darwin10-unwind-find-enc-func.c: Include libgcc_tm.h.
	* config/i386/darwin-lib.h: Declare Darwin10 crt function.
