Subject: Darwin, libcc1: Handle hosts with mdynamic-no-pic support.
X-Git-Tag: releases/gcc-10.4.0~88
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1265bfa73a4334879170bb10854abcff5c17e501;p=thirdparty%2Fgcc.git

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.
