Using libtools and autoconf with nios2

Hi,

I would like to build a GNU tool that comes as an auto-configure distribution for inclusion in my uClinux filesystem. Has anyone succesfully ported to --target nios2-elf?

I am newbie on autoconf and libtools, I have looked at (tried to digest) the Ben Elliston, Tom Tromey... book, but still not been succesful, any clues please?

Many Thanks,

Dave
