I noticed this was showing up on profile logs as a sigificant time user in "bitbake bash" when bash was already built. It reduces the time from 5.2 to 4.5 seconds in my test environment. We make use of the parser's mtime cache as once a directory exists, we can assume it continues to exist and this avoids syscalls. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> ---
