  Starting at around 2.6.4-rc2-mm1, I keep seeing 'scripts/fixdep: Text
  file busy' messages when doing a -j10 bzImage build - which seems to
  suggest that by the time fixdep is used by the build system it's not
  built yet.

I was pretty sure it was something I had caused, so I gave it a spin.  What
actually happened was that we tried to build the target 'silentoldconfig'
in parrallel with 'scripts'.  Since 'silentoldconfig' started a new make
and then the config target needed 'scripts' we saw two parallel runs.

The way I decided to fix it was to split scripts/ in two parts.  The first
part is now the very basic stuff - moved to scripts/basic/.  The second
part is dependent on kernel config etc.  and kept in scripts/

In the 2.7 timeframe i will redo this initial stuff - it's becoming too
messy for anyone to understand today.


Description:

Fix dependencies in early phases of kernel build.  This solves a few
problems nively: modpost is no longer rebuild twicewhen reaching the
'target' state 'make -j10' now works nicely again

The patch is rather large due to the following file moves:
mkdir scripts/basic
mv scripts/fixdep.c        scripts/basic
mv scripts/split-include.c scripts/basic
mv scripts/docproc.c       scripts/basic
