Okay, building a gcc to run on the target is not (yet) supported, and I
think doesn't work for the imx (it works for most powerpc though)

The host based cross toolchains are pre-built.  The reason is that we
need to have known tested binary toolchains to take them out of the bug
reporting equation.  Unless a toolchain is known to be good, anything
you build with it is a gamble.

Yes, that would be right, but unfortunately it's not supported for the
imx31

Yes, normally.  You'll need to work on a new spec file if you want to
get this running (e.g. gcc-411-gnueabi-nptl) unless we can merge all the
changes into a common spec (which is not that likely).

BTW: Why do you want to have a gcc to run on your imx31?
