assimp: disable on Microblaze
This package triggers an infinite loop bug in gcc on the Microblaze architecture when the optimization level is O1, O2 or O3. This bug has been reported at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71124. While Buildroot by default uses an Os optimization level, assimp's build system overrides that by O3 by default. This problem is causing timeouts in the autobuilders that make them consume 100% of CPU during 8 hours (the timeout used by the autobuilder scripts). Fixes: http://autobuild.buildroot.net/results/084fc537ab81aed278126f173daf99f2699ef22c/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
