If you use --disable-nls on the configure line, the intl directory
should be skipped ...

Before including "system.h", generator files include "bconfig.h"
where core compiler files include "config.h".  The former then
in turn includes "auto-build.h", while the latter includes
"auto-host.h".  These contain the configure results for the
--build= and --host= systems, respectively.

All this should work automatically if you use the proper
configure options, so something odd must be going on ...

Are you running the top-level configure?  (If you run a
subdirectory configure, e.g. the one in gcc/, directly,
things may not work correctly.)

Bye,
Ulrich
