Subject: configure.ac: make grep tests more portable
X-Git-Tag: mesa-9.2.1~239
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F39%2F7539%2F1;p=platform%2Fupstream%2Fmesa.git

configure.ac: make grep tests more portable

Use grep -w instead of the empty string escape sequences
which are less portable.  Makes the grep tests
function as intended on OpenBSD.
