Do not set STAGE1_CFLAGS, you may run into bugs of the bootstrap compiler.
And I am still getting floating point exception even with a bare make. Any way to debug this?

Paste the failing gcc invocation from your make output into the shell but add -v so you can see the commands passed to the various compiler components.

Then run the failing component in gdb with a command similar to that reported by gcc -v.

At least that is the way I would do it.
