[yocto] Running builds under strace

[Alex deVries]

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!
