    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.
