Valgrind compiled on kernel 2.4.22 gcc version 3.2.3, run on kernel 2.4.24 gcc version 3.2.3
It's only gives the "Illegal instruction" from the Valgrind script exec command for any program run, including the pwd command.

Try 2.1.1 or later. There was a period when it was assuming that
the processor was SSE capable and I think you're falling foul of
that. Current versions (2.1.1 or 2.1.2) should handle that properly.

What version of valgrind is this?

It may be a CPUID instruction or something - not all 486s have that.
To be honest valgrind is going to be so slow on a 486 that you're
probably going to find it very hard to use.
