Following reproducible-builds.org recommendations, using compiler flags
like -ffile-prefix-map or -fdebug-prefix-map allows replace build-time
paths by install-time ones in the debugging sections of binaries.

Variable DEBUG_PREFIX_MAP set these flags correctly in yocto build
context to guarantee reproducible builds.
