Subject: libcody: Allow PIC [PR 98324]
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d1ad55c4e08b827b4d38f763e0427096305d460d;p=gcc.git

libcody: Allow PIC [PR 98324]

While this doesn't fix 98324, it was an omission.  Cribbed code from
libcpp to build libcody as PIC.

	libcody/
	* configure.ac: Add --enable-host-shared.
	* Makefile.in: Add FLAGPIC.
	* configure: Regenerated.
