The clean command line compiler clm checks modules for freshness by comparing timestamps.
However, in chroot builds all files installed have the same timestamp. This leads to clm
trying to rebuild the library modules distributed with the Clean install every time a user
compiles any file. This patch changes the freshness check to use less than instead of less
than or equal to in order to avoid this.
