<cut>
2.4.19-pre8-ac1:
$ time make dep clean bzImage modules
...
real 6m22.176s

$ time su -c 'make modules_install'
...
real 0m6.963s

----

2.4.19-pre8-ac2 + patch-2.4.19-pre8-ac2-kbuildfix2:
$ time make dep clean bzImage modules
...
real 5m57.509s

$ time su -c 'make modules_install'
...
real 0m2.255s
<cut>

> kbuild mantra - correctness first, speed second.
