[OpenBIOS] OpenBIOS fails to build on sparc32/64 hosts

[Aurelien Jarno]

Hi,

Trying to build OpenBIOS natively on sparc32 or sparc64 host, I get the following error:

LINK  openbios-unix
libopenbios.a(load.o): In function `load':
/home/aurel32/openbios-devel/obj-sparc32/../libopenbios/load.c:41: undefined reference to `sys_info'
/home/aurel32/openbios-devel/obj-sparc32/../libopenbios/load.c:41: undefined reference to `sys_info'

It seems only sparc32/64 have CONFIG_LOADER_AOUT. The sys_info variable is defined in 
arch/sparc{32,64}/boot.c, but this file is not used to build openbios-unix. Any new what would be 
a real fix here, besides disabling CONFIG_LOADER_AOUT?

Thanks,
Aurelien
