Why is LIMITS_H_TEST defined in cris/t-linux? It caused cross-compiler build errors

[Stephen M. Kenton]

Can anyone explain why LIMITS_H_TEST is defined in cris/t-linux, while 
it is not defined for any other linux target?  It's a relatively recent 
change. "ChangeLog-2005" line 5810 says

"2005-10-12  Hans-Peter Nilsson  <hp@axis.com> config/cris/t-linux 
(LIMITS_H_TEST): Define."

It breaks building of a cross-compiler when inhibit_libc is defined, and 
the comment in the code

# We *know* we have a limits.h in the glibc library, with extra
# definitions needed for e.g. libgfortran.

is certainly wrong in this case.  It it just an optimization?  Can it be 
done some other way that does not break building a cross-compiler? A 
one-liner to comment this out allows me to build a cris cross-compiler.

Segher - If remember right, cris was one of the targets that did not 
build for you. This might help.
