autoconf: Tolerate missing file when grepping.

Currently we die when grepping for compatibility strings if the
file does not exist.  Since this can be a valid situation when
files are added in later versions, we shouldn't kill the build.
Instead, note that the file doesn't exist but otherwise treat it
as if the string was not found.
