[Ltib] Busybox building breaks on QuadCore box

[Peter Barada]

I've run into a sporadic problem building busybox on my I-720 QuadCore box running Ubuntu-9.04x64.  It looks to be a timing problem where busybox launches the build of applets/appletlib.o before it completes the generation of include/usage_compressed.h.  I've seen this problem with LTIB's patched 1.11.2, as well as an unpatched 1.15.1.  The following is a clipped log of the build of 1.15.1 with the pertinents bits in bold:

error: Bad exit status from /home/peter/work/logic/svn/eps_svn/software/products/linux/LTIB/tags/REL-ltib-1_61/tmp/rpm-tmp.121 (%build)

I've tried adding the following dependency to applets/Kbuild:

applets/appletlib.o: include/usage_compressed.h

And this apparently rearranges the build such that include/usage_compressed.h is generated before applets/appletlib.o is built, but I'm not sure if this the correct approach.  Has anyone seen this before?  Does anyone have a better suggestion on how to fix this?  Are there any other dependency gotchas I'm missing?
