@@ -6,18 +6,12 @@ Subject: [PATCH] llvm-config: Clean up exported values, update for shared
 
 Gentoo-specific fixup for llvm-config, including:
 - wiping build-specific CFLAGS, CXXFLAGS,
-- updating library suffixes for shared libs,
-- making --src-root return invalid path (/dev/null),
-- making --build-mode return "Release" rather than "Gentoo".
+- making --src-root return invalid path (/dev/null).
 
 Thanks to Steven Newbury for the initial patch.
