the first problem i faced was the Makefile complaining about an empty
default environment path, though CONFIG_DEFAULT_ENVIRONMENT is not defined:

# CONFIG_DEFAULT_ENVIRONMENT is not set

matze@darwin:/tmp/barebox-2009.12.0$ make
Makefile:1274: *** default environment path empty.  Stop.

this one was easy to work around by commenting the offending section
in the Makefile

reproducing it is as easy as "make ARCH=sandbox menuconfig;
<exit_and_save>; make" from a clean environment

i wasn't able to solve or work around the next one:
