Dependencies run at the wrong time.

[Rob Landley]

I have a .config file from the 18th or so, and since we've two applets to svn 
(fuser and switch_root).

When I build the new snapshot with the old .config file, it runs oldconfig and 
stops and prompts me (at fuser, and at switch_root).  Then the compile 
continues until it dies with:

/tools/tmp/busybox-1.1.0-pre1/applets/applets.a(applets.o):(.rodata+0x318): 
undefined reference to `fuser_main'
/tools/tmp/busybox-1.1.0-pre1/applets/applets.a(applets.o):(.rodata+0x7b0): 
undefined reference to `switch_root_main'
collect2: ld returned 1 exit status
make[1]: *** [busybox] Error 1

Anybody with makefile-fu want to move the dependency checking until _after_ 
we've run oldconfig?
