[Buildroot] [PATCH 1/2] package: instrument to gather timing data

Sun Oct 9 16:17:27 UTC 2011


Instrument the package infrastructure to generate a
$(O)/build-time.data file which contains one line for each step of
each package and the corresponding duration in milliseconds.

The instrumentation is not perfect yet, as it doesn't account for
packages with overriden source directory and the build-time.data is
never removed, so results will accumulate if several partial builds
are done.
