[OpenBIOS] Compiling Openbios with Sparc cross compiler

[Paul Wilhelm]

On the machine that does compile, the following file is used:
/usr/include/bits/sigcontext.h
This file has a copyright of 2002 from FSF.
This file does not try to use __u32, etc, and does not include other files
that do.

On the machine that fails to compile, the following file is used:
/usr/include/i386-linux-gnu/bits/sigcontext.h
This file has a copyright of 1998 from FSF. This includes asm/sigcontext.h
which in turn includes linux/types.h before using __u32, etc. linux/types.h
includes asm/types.h (which in other other circumstance would include other
files that include the definition for __u32, etc.). With the asm/types.h in
target/include, things get broken.

I did some googling to find out how the /usr/include/bits directory gets
filled, what package might set that up, but, I did not find anything useful.

Any suggestions?
