how to build and test uClinux toolchains

[Christophe Lyon]

Hi,

While reviewing one of my patches about FDPIC support for ARM, Richard
raised the concern of testing the patch on other uClinux targets [1].

I looked at uclinux.org and at the GCC maintainers file, but it's
still not obvious to me which uClinux targets are currently supported?

I'd like to do a basic:
- build toolchain for target XXX, make check
- apply my GCC patch
- build toolchain for target XXX, make check again
- compare the results to make sure I didn't break anything

I'd appreciate hints on which targets offer to do that easily enough,
using a simulator (qemu?).

Thanks,

Christophe
