linux-user/hppa: Increase guest stack size to 80MB for hppa target

Browse source 
The hppa target requires a much bigger stack than many other targets,
and the Linux kernel allocates 80 MB by default for it.

This patch increases the guest stack for hppa to 80MB, and prevents
that this default stack size gets reduced by a lower stack limit on the
host.

Since the stack grows upwards on hppa, the stack_limit value marks the
upper boundary of the stack. Fix the output of /proc/self/maps (in the
guest) to show the [stack] marker on the correct memory area.
