This kinda sounds like you're using object code compiled for > i386 (ie
i486, i686) on your 386.  The message implies that it's an instruction
the CPU does not understand, and since intel tries to maintain backward
compatibility, it's probably a newer instruction, not an older one.

If you want to follow on my supposition, verify that the uClibc is built
for 386 as well... and since the 386sx has no FPU, you'll need to define
some floating point support in uClibc.

Check to see if the same error occurs with a static-linked busybox. 
...I'm assuming you have some other binaries in-use, so you're linking
bb against uClibc to share libs with those other binaries.
