[patch] bsdbox changes for base system: add LOCAL_

Hi,

Here are two patches which implement some useful features for crunch building:

* Add LOCAL_TOOLS_DIR in src/Makefile.inc1, which adds entries to the
'build-tools' target. This is needed for cross-building bsdbox (and
any external directory added by LOCAL_DIRS)
* If CRUNCH_SUPPRESS_ALL_LINKS is set to 'yes', don't auto-populate
the crunch-gen hard links.

I may end up changing the latter to CRUNCH_GENERATE_LINKS and default
that to yes, then allow the bsdbox build system to change that to
'no', but the intent is the same.

I'd like to commit this tomorrow if possible, so I can then follow it
up with the bsdbox import.

Thanks,


Adrian
