There isn't much difference between the first patch and the second one except that 
the first patch was made to build and link in 64-bit, whereas this second patch has 
the relevant changes to compile and run in 32-bit mode. This is because Ultrasparc 
runs only the kernelspace in 64-bit mode with userspace still running in 32-bit, 
which make it necessary to compile and run uml as 32-bit executable for it to be able
to run in userspace.

- Made some significant changes to ptrace files.
- Changed the registers that ptrace accesses, to sparc target instead of sparc64.
- Removed non-technical additions like whitespaces and redundant files form first patch.
- Removed the dependency of Makefile on gcc-3.0.4 as was present in previous patch.
- Removed cross-compiler option (sparc64-linux-) from top level Makefile.
- Changed the link file for sparc target and also allow it to run in any address space 
	as it wants.
- Added sigcontext.c for sparc64.
