more troubles with SuSE 9.2

[Ray Bryant <raybry at sgi dot com>]

Actually, I'm not sure that this probem is specific to SuSE 9.2, it is 
just where I am encountering it.

I am running on i386, trying to build a cross-compiler for ia64.  
Consistently, whenever the script
gets around to trying to (cross) compile some ia64 assembler code, that 
step fails with an "as: -x unrecognized
option" error.   For example, I encounter the following:

make[1]: Entering directory

Now the problem really is that xgcc is finding and invoking /usr/bin/as, 
which is the i386 assembler, which
doesn't understand the -x option.  (Indeed, if I replace /usr/bin/as 
with a symbolic link to the ia64 assembler,
this step completes, but then the build fails the next time we need to 
invoke the host assembler again).

This seems like a pretty fundamental problem in the cross compiler 
domain.   I mean, if you can't even
get the right assembler invoked, you are pretty much hosed.

So my questions are:

(1)  Is this a problem for other Linux systems other than SuSE 9.2?
(2)  Can anyone think of a better workaround (the other one I've come up 
with is to preprocess the files
by hand, and then invoke the ia64 assembler directly instead of invoking 
xgcc, but that is prone to
problems as well [getting the right include files found can be 
difficult....]).

Best Regards,
