From ddddc7335539fb8a6d30beba21781762df159186 Mon Sep 17 00:00:00 2001

Subject: [PATCH 42/47] Reuse -fdebug-prefix-map to replace -ffile-prefix-map
The oe-core may use external toolchain to compile,
which may not support -ffile-prefix-map.
Since we use -fdebug-prefix-map to do the same thing,
so we could reuse it to replace -ffile-prefix-map.
Upstream-Status: Inappropriate[oe-core specific]
