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.
Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
libcc1/ChangeLog:
* Makefile.am: Switch mdynamic-no-pic to fPIC.
* Makefile.in: Regenerated.
