Hi!

We run both little and big endian Arm targets at work. Currently both
are Arm9 so naturally I started thinking about creating one single
toolchain to bind them all...

I put together a standard arm-unknown-linux-uclibc with crosstool and
building the kernel worked fine using "-mbig-endian -mcpu=xscale
-mtune=xscale -msoft-float", but when I reached userspace the first
effort at linking with libgcc of course failed.

So I wonder, is it even possible to maintain one toolchain supporting
different endians?

Generally speaking, of course it is. What you are looking for is a big/little endian multilib'ed toolchains.
