[ELDK] Ubuntu 12.04 and ELDK 4.1

Hello Stefan,

No, it is kind of tricky to use another libc and it required too much work.
I have reverted back to 11.10 instead.

I can make the compiler kind of work depending where it is installed, how
many softlinks it resolves and such.

I am not the only one with problems running Ubuntu 12+ and ELDK 4.2, I have
tried cleanly installed system as well and they have these odd symptoms with

The best thing would probably be to recompile the compiler with the same
cross tool settings under Ubuntu 12.04, which I might try later, but at the
moment I don't have that time so it is easier to revert back.

Do you have a working 12.04 with libc 2.13 ? I do not think it is the
problem. I have a 12.04 (yes, updated from previous version) with libc 2.15,
ELDK-4.2 is working.

And ELDK-4.2 is not so strict that should be installed. I moved it often to
another system copying everything (in a tarball) under the eldk-4.2
