From c84a3458aaee23b6cc6a6ace039596dccb6b7a12 Mon Sep 17 00:00:00 2001 From: Rosen Penev Date: Fri, 3 Jan 2020 18:31:01 -0800 Subject: [PATCH] libcxx: Remove -flto from LDFLAGS It seems the buildbots can't handle it. Added a cmake option to find the cxxabi files as they are part of the toolchain and not in the normal path. It doesn't seem to make a difference, just gets rid of cmake warnings. Added another small GCC warning fix. It's fairly minor. This has no change in compiled size, and most likely no change in behavior. Bumped the PKG_RELEASE anyway.
