Description of Problem:

I tried to do:

(1)sparc32 rpm -bb gcc.spec --target=sparc-redhat-linux
(2)rpm -bb gcc.spec --target=sparc-redhat-linux
(3)rpm -bb gcc.spec
(4)rpm -bb gcc.sprc --target=sparc64-redhat-linux

with differents results:
(3) & (4) : -m64 not suported,
(1) & (2) :
Assembler messages:
Fatal error: No compiled in support for 64 bit object file format
make[3]: *** [libgcc/64/_muldi3.o] Error 1
make[2]: *** [stmp-multilib] Error 2
make[1]: *** [bootstrap-lean] Error 2
make: *** [bootstrap-lean] Error 2
error: Bad exit status from /var/tmp/rpm-tmp.51978 (%build)
    Bad exit status from /var/tmp/rpm-tmp.51978 (%build)

Idea: is a binutils problem? need --enable-targets=sparc64 in configure of
binutils when you build sparc target?

How Reproducible:
try to compile last gcc rawhide package in ultrasparc

Actual Results:
If you need, I can submit stdout an stderr of each try.

Additional Information:
As you can see, english is not my first language	

Additional question (off topic?):
- Do you know why no more binary buils for sparc is in rawhide mirrors?
- Do you know if RedHat will adopt gcc 3.0?

Thanks so much in advance.
