Improve the portability of grep patterns in configure.ac

The configure.ac script uses backslash plus in its grep patterns to
match one or more occurrences.  This is a GNU grep extension to the
Basic Regular Expressions syntax that fails on systems with a more
traditional grep.  This changes fixes grep patterns that use backslash
plus to use a star instead.
