Note that some people might expect this behavior.  For instance, many
RCS-controlled projects insert a version string in each file like:

static char rcsid[] = "$$RCS$43278$foo$bar$baz";

Since this is compiled in to the binary, one can tell what version of
each source file went into a given binary.  If ld removed it, this would
break.
