[PATCH 11/12] ltmain.in: Handle prefix-map compiler options correctly

Richard Purdie <[email protected]> Mon, 25 Oct 2021 15:33:36 +0100
Newsgroups gmane.comp.gnu.libtool.patches
Message-ID <[email protected]>
If lto is enabled, we need the prefix-map variables to be passed to the linker.
Add these to the list of options libtool passes through.
