GCC releases are distributed as tar files, where the files generated by flex
and bison are included with timestamps set so that they will not be
regenerated.  The comments in the configure script refer to that situation.  If
you check out gcc (or llvm-gcc) from subversion, the timestamps on the files
may not conform to that expectation.  If the timestamp on a generated file is
older than the source file, flex or bison will be run.  This is not the ideal
situation, but since it is inherited from gcc, it's not something we need to
fix for llvm-gcc.
