[Qemu-devel] RFC: fix run of 32 bits Linux executables on 64 bits targets

[J. Mayer]

Following the patches done for elfload32, it appeared to me that there
were still problems that would prevent 32 bits executables to run on 64
bits target in linux user mode emulation.
First of all, the personality was never set to PER_LINUX32
The second problem was that pointers used to set the values on the stack
were still of target_ulong size, which lead 32 bits executable crash
dereferencing NULL pointers as soon as they wanted to parse their
arguments.

The attached patch makes 32 bits PowerPC executables run in
ppc64_linux_user target. More fixes may be needed in the start_thread
function and elf_check_arch to make other targets run as well.

Please comment.
