Maybe capture this in Bugzilla? (Not at my computer at the moment or would help). Thanks again.

Subject: [yocto] Running builds under strace
I'm working on swabber support, and as part of that need to enable running builds in strace. The code for this is in josh's poky-contrib.
For anyone else who is looking at this, various packages failed to build with -jN (with N>1). My theory is that running these builds under strace changes the build timing and exposes existing parallel build problems that don't normally show themselves.
To address this, I had to modify various recipes to set PARALLEL_MAKE = "" for various packages.
The following packages had to be modified:

The only really concerning ones were eglibc and gcc. We can't set PARALLEL_MAKE="" for these as these are very large, and builds would be very slow. Packages like popt don't matter as much, you don't save that much time by building them with -j16.
Josh and I are trying to figure out how to address these.
Swabber support is coming soon!
