[pull,request,v2] Pull request for branch yem-instrument-build

Hello All!

This series adds some intrumentation to the pkg-infra so that it is easier
for the autobuilders to extract meaningfull information about the reason
of failures.

It does so by:
  - logging all messages displayed with calls to MESSAGE to a time-stamped
    log file
  - log the last such mesage to a file
  - add calls to MESSAGE in the non-package steps of the external toolchain
    backend
  - add calls to MESSAGE in the non-package steps of the crosstool-NG
    toolchain backend
  - add calls to MESSAGE in the non-package steps of the internal toolchain
    backend (gcc, kernel headers, and uClibc)

Although I've tested it with external and internal toolchain backends (not
crosstool-NG for now), and although it does work, I expect some polishing
to be required. 

So, take this series as a kind of RFC, rather than a final series.


Changes v1 -> v2:
  - invert the patches ordering for easier upstreaming (Thomas)
  - include Arnout's fixes against the filesystem infra (Arnout)
    (with a few fixes for "no newline at end of file" by me)
  - eye-candy fixes in displayed messages (Arnout)

Arg! Arnout's authorship was lost when I added his patch to my tree... :-(
Let me fix that...

[git-am choked on the patch because of some missing "newline at end
of file", hence I applied it manually, and forgot to change authorship]

OK, the branch on gitorious has been fixed, now. Not re-sending the series,
though. Please pull form gitorious to ensure Arnout's authorship is
retained.

My apologies for the hiccup. :-(

  Funny, must be a bug in git-apply.

  Regards,
  Arnout
