Confirming here. This seems to be due to a pentium-4 specific optimization done at the build farm, see http://launchpadlibrarian.net/21608730/buildlog_ubuntu-jaunty-i386.mjpegtools_1%3A1.9.0-0.0_FULLYBUILT.txt.gz.
The configure-script passes -march=pentium4 -mtune=pentium4 to gcc which I think is the cause for the failures.
