From: Changqing Li <[email protected]> DEBUG_PREFIX_MAP is appended to TARGET_LDFLAGS in commit [1] for fixing reproducible issue when LTO is enabled. It is removed in comit [2] since this commit causes cgo binary not reproducible. But actually, we still need this DEBUG_PREFIX_MAP in LDFLAGS when LTO enabled. So, only appened it when LTO is enabled. Refer [3] for the history, with this patch, patch [4] is also needed for cgo + lto enabled.
