I have limited access to one powerpc system out on the net, 
so I'll try it out there now and see how it behaves.

Ok.  Things compiled up just fine.  Here are a few details about
the system:

$ uname -a
Linux voltaire 2.4.18-powerpc-smp #1 SMP Thu Mar 14 19:59:10 EST 2002 ppc unknown
$ cat /proc/cpuinfo 
[------snip------]
total bogomips  : 1985.74
machine         : PowerMac3,3
motherboard     : PowerMac3,3 MacRISC Power Macintosh
L2 cache        : 1024K unified
memory          : 320MB
pmac-generation : NewWorld

Testing out the latest and greatest busybox with the latest
and greatest uClibc, this is what I get:
 
$ ldd ./busybox
        libc.so.0 => /home/andersee/usr/powerpc-linux-uclibc/lib/libc.so.0 (0x0x30016000)
        ld-uClibc.so.0 => /home/andersee/usr/powerpc-linux-uclibc/lib/ld-uClibc.so.0 (0x0x30000000)
$ ln -s busybox date
$ ls -l ./date
lrwxrwxrwx    1 andersee Debian          7 Jun 26 19:24 ./date -> busybox*
$ ./date 
Wed Jun 26 23:24:28 UTC 2002
$ ./date -u
Wed Jun 26 23:24:33 UTC 2002
$ ./date -u -u
Wed Jun 26 23:24:35 UTC 2002
$ ./date -u -u -u
Wed Jun 26 23:24:39 UTC 2002
$ test1= ./date -u -u -u
Wed Jun 26 23:24:45 UTC 2002
$ test1= test2= ./date -u -u -u
Wed Jun 26 23:24:51 UTC 2002


So everything works just perfectly for me on this powerpc system.
Wish I could help you, but i'm just not seeing the problem,
