Reg. sparc64 linker error

Hi,
I am trying to port user-mode-linux(uml) to Sparc64 arch. I am running a custom built 2.4.18 kernel on debian (sid), Ultra 1 system. I have also created static links sparc64-linux-ld and sparc64-linux-as. When I build the uml sources, I am getting the following linker error:

gcc-3.0 -Wall -Wstrict-prototypes -Wno-trigraphs -O2

(quoted diff) +0 -6

I am using gcc-3.0 with binuitls 2.12.90.0.0.1-5. When I tried using gcc with egcs64, it gave me a bunch of parse errors. Hence, I switched to gcc-3.0. But now, I have this linker error. Any pointers in this direction would be appreciated.

gcc-3.0 may not work well. Eitherway, copy the CFLAGS/LDFLAGS from arch/sparc64/Makefile. For this example above, you are missing -m64 as an option to make it output 64bit executables.
