compile busybox on a Pentium3 for Pentium-mmx = segmentation fault

[Felipe C.]

Let me try again:

I don't have any problems compiling bb. It works just fine no matter the
configuration. I even know that the executable works (on any machine with a
Pentium 2 or better). When I run it on the Pentium mmx I get a segmentation
fault.

What I am trying to figure out is how to tell busybox to compile without the
default optimizations for the current host. The only way out that I figured
out so far was to create a gcc cross-compiler with target=i586 and then
change the busybox configuration to use it. It works but I would assume that
there must be an easier way to compile the busybox using the host gcc as
long the host and the target share the same architecture  (something like
compiling the kernel - I can compile it for any x86 on the i686 using the
standard gcc).

Thanks
Felipe
