Subject: check-exports: Use the return code of diff rather than the output
X-Git-Tag: upstream/20130618~212
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9996f728e7aa207cafd904c2d2ed87fe02c9accc;p=platform%2Fupstream%2Fgst-common.git

check-exports: Use the return code of diff rather than the output

diff on Solaris prints 'No differences found' for matching files, which
makes the check-exports call fail regardless of whether the exports match
or not. Instead, use the return code of diff, which is 0 when the files match.
