| Series | [meta-oe] bpftool-native: Empty DEBUG_PREFIX_MAP_EXTRA | expand |
Hmmm... this doesn't sound right. DEBUG_PREFIX_MAP_EXTRA supposed to be set only for class-target. This sounds like a possible bug in oe-core: maybe it should get a weak-default value in gcc.bbclass, and a strong (empty) assignment in gcc-native.bbclass?
