busybox buildlogs, script

[Bernhard Fischer]

Hi,

http://busybox.net/~aldot/mk.busybox.sh

is a quick and ugly script used to check for compile-regressions
in busybox.

Currently it does compile busybox with one applet enabled:
for each base-applet
  for no feature selected and each feature of the base-applet
    for each buffer-allocation scheme (malloc,stack,bss)
      turn cleanup off and on

It currently does not compile the NxM Matrix to iterate over all
applet-combinations.

The script was run on a not too current PC with make -j and the now
reverted buildsystem infrastructure ¹) and glibc and took about 12
hours to run.

I hope that the exposed errors are of use for somebody :)
