Hi,
I wanted to test the kinit setup on my configuration, and I found out
that I'm unable to build using an external object directory
(i.e. using O=../dir). I'm using the sources from the GIT tree.
The first problem is in usr/dask/Kbuild, in the invocations of mktokens;
with O= the build system will try to execute something like:
/home/.../linux-2.6-klibc.git//home/.../linux-2.6-klibc.git/usr/dash/mktokens
which of course fails. I'm using the following patch to fix this issue:

(in case you want it)
diff --git a/usr/dash/Kbuild b/usr/dash/Kbuild
index 4e75324..452d066 100644
--- a/usr/dash/Kbuild
+++ b/usr/dash/Kbuild
@@ -66,8 +66,8 @@ $(obj)/check:
# Generate token.h
quiet_cmd_mktokens = GEN $@

+ cmd_mktokens = cd $(obj); sh $<
+$(obj)/token.h: $(srctree)/usr/dash/mktokens
$(call cmd,mktokens)
# Generate builtins.def
The problem is that when building without O= $(src) contains the
relative path of mktokens (usr/dash), which combined with $(srctree)
gives the correct path; when building with O= $(src) contains the
absolute path of the sources (/home/.../usr/dash). Since the output of
mktokens is hardcoded to token.h in the current dir I had to hardcode
the relative path of mktokens in the rule; another solution could be
changing mktokens to output on the stdout and redirect it to the correct
file.
I've tested the patch with and without O= and it works as expected.
The compilation then stops at dash anyway, with the following error:

This does not happen without O=, and I don't know what's going wrong :(
