Removing gcc and binutils leave some files around the system that aren't needed anymore. Specifically, /usr/share/gcc-data/(old_version) and /usr/share/binutils-data/(old_version) because the dir.old file in the info directory is not removed. Reproducible: Always
portage should clean out info files from INFOPATH automatically
This is fixed in svn r7774.
This has been released in 2.1.3.10.
