configure.ac: change regex for sed versionptxdist-2013.01.0
Change regex for sed version in configure.ac. This regex will match only on the first line and doesn't look for a 'version' pattern which is not available in sed version 4.2.2. The new regex will match in the first line of 'sed --version' in a pattern which starts with random character sequence(or zero) followed by whitespace character and several digits of pattern x.x....x which x is a number. This pattern will be save in the SED_VERSION variable. Signed-off-by: Alexander Aring <alex.aring@gmail.com> [mkl: add match for GNU in regex] Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
