It *does* make my life easier!

I'm not just using it for personal stuff, but for lots of highly
customized production systems, where careful maintenance is
very important.

Disk space is not the issue, but the amount of code to be
maintained (source and binary). So the target systems *always*
should only contain exactly what's needed - nothing more.

Actually, I want to make it simpler. You probably can't see this
since you don't know what happens behind the scenes at my site ;-P

One essential constraint is, that everything's built through an
sysroot'ed cross-toolchain. Right after compile several checks
run on the output, packages are then trimmed-down (eg. removing
all build-time stuff) and then it goes to the testing system.
Only after the whole pipe ran through properly, the binary
package is committed to the production systems.

The current approach already fails with crosscompiling.
I *can not* use the in-tree built mk for further building
and I *must* make sure that imports are strictly coming
from within sysroot.

You shouldn't generally declare this approach as horror,
just because autoconf is a horrible example.
