We keep occasionally seeing:
http://autobuilder.yoctoproject.org:8011/builders/nightly-mips-lsb/builds/310/steps/Building%20Images/logs/stdio
which is a failure in target gcc due to the use of the dependency
tracking. I think the dependency tracking code does have some kind of
races in it :(.
Do why know why we can't turn off the dependency tracking in libatomic?
Are there any upstream bug fixes for this?
Cheers,
Richard
