[oe] Compile OE on Sun Ultrasparc 64 architecture?

[harald]

Hello,

tried to compile OE on my Sun Ultrasparc 64 machine running on debian
lenny. 
Compilation fails, package qemu-native fails to compile with an error in
zlib. please see build logs, machine h4000, user ba0547.

i have changed a value for architecture from sparc-linux to
sparc64-linux becuase sparc64-linux has not been found and cmpilation
does not even start.

please tell me what to do to resolve these errors.

Regards, harald.
