config.sub generation bug?

[ORMANCEY Nicolas]

Hi joel,

You're right
The message is exactly 
Invalid configuration ` myCPUfamily -rtems ': machine ` myCPUfamily ' not
recognized

I did like you by copying a score/cpu directory and modified the 
configure.ac and Makefile.am files

I have created (by copy) the tree contrib./crossrpms/rtems4.8/myCPUfamily/
And modified files to be as close as possible of the source tree
configuration 

But myCPUfamily don't appear in the config.sub file

Thanks

Invalid configuration `joel-rtems4.10': machine `joel' not recognized

What exactly is the output from config.sub?

And if it doesn't give a message like above, what is the EXACT error 
from configure.

Do you have a score/cpu directory yet? I don't recall the checks in 
place because
I always copy stub files into a new cpu when I start and add it to the 
configure.ac
and Makefile.am as appropriate. I like to have things compiling before I 
hack.

Also it will eventually check for myCPUfamily-rtems4.10-gcc or whatever the
full target name is.  You need to address that with symlinks or something.
