Hello Paul,

I've been trying to setup your test suite on my powerpc board but it's 
based on Perl and on a lot of optional Perl packages. I was able to add 
them one by one until some of them require some .so libraries 
(Pathtools-Cwd), and it seems nothing is made to allow cross building 
those libraries.

Do you have another test suite based on C and not perl ?

If not, what can I do, do you know how I can cross compile those Perl 
packages for PPC32 ?

Thanks
Christophe
