Subject: * libtool.m4 (LD): Append -melf* option to LD on IRIX with GNU ld.
X-Git-Tag: binutils-2_14-branchpoint~788
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f4ff34a3047cd5dafebeeb733559c5dc0dba2339;p=external%2Fbinutils.git

* libtool.m4 (LD): Append -melf* option to LD on IRIX with GNU ld.
* ltconfig: Handle it.
* ltcf-cxx.sh: Use with_gnu_ld passed as a shell variable instead of
auto-detecting it.
