Darwin, libcc1: Handle hosts with mdynamic-no-pic support.

The default for building host-side binaries for mdynamic-no-pic
hosts is to enable this.  However, it is not compatible with
dynamic libraries, so must be switched off for libcc1.

libcc1/ChangeLog:

	* Makefile.am: Switch mdynamic-no-pic to fPIC.
	* Makefile.in: Regenerated.
