It's not about POSIX now. As I said, an old config was not being
overwritten and was still generating posix-disabled builds. I've redone it
   from scratch and it works now. Now it's about waf spitting out errors  
that
are not there when using make.

If I change to a specific example directory and run make, no problem. When
I use waf (in local dir or in the root of examples-v2), it exits with the
error posted above, or here for convenience:
sparc-rtems4.11-gcc: fatal error:
/opt/rtems-4.11//sparc-rtems4.11/sis/lib/bsp_specs: attempt to rename spec
'endfile' to already defined spec 'old_endfile'
compilation terminated.

Waf is configured (hopefully) fine. Otherwise it wouldn't even try to
build. Has anyone had any similar problem?

waf configure was run with these options: --rtems=/opt/rtems-4.11/
--rtems-tools=$HOME/development/RTEMS-tools/4.11 --rtems-bsps=sparc/sis

I honestly don't even know what the error means, I've never used bsp_specs
files before.
