kbuild: install all headers when arch is changed

We see some header files that are selected dependent on
the actual architecture so force a reinstallation
of all header files when the arch changes.

kbuild: install all headers when arch is changed

We see some header files that are selected dependent on
the actual architecture so force a reinstallation
of all header files when the arch changes.
This slows down "make headers_check_all" but then
we better reflect reality.

kbuild: optimize headers_* targets

Move the core functionality of headers_install
and headers_check to two small perl scripts.
The makefile is adapted to use the perl scrip and
changed to operate on all files in a directory.
So if one file is changed then all files in the
directory is processed.

perl were chosen for the helper scripts because this
is pure text processing which perl is good at and
especially the headers_check.pl script are expected to
see changes / new checks implmented.

The speed is ~300% faster on this box.
And the output generated to the screen is now down to
two lines per directory (one for install, one for check)
so it is easier to scroll back after a kernel build.

The perl scripts has been brought to sanity by patient
feedback from: Vegard Nossum <vegard.nossum@gmail.com>

kbuild: only one call for include/ in make headers_*

Move it to the top-level file to decide if we install/check
the generic headers or the arch specific headers.

This revealed a long standing bug

kbuild: only one call for include/ in make headers_*

Move it to the top-level file to decide if we install/check
the generic headers or the arch specific headers.

This revealed a long standing bug where "make headers_check_all"
relied on the files in asm/ for the current architecture.
So make headers_check_all is now broken by this commit.

In addition:

o add a simpler way to detect if an arch support
exporting header files.

o add 'set -e;' so we error out early if
make headers_check_all fails.

o add sparc64 and cris to arch we do not process
in make headers_*_all because:

sparc64 - use sparc to export headers
cris - is know seriously broken
