linux-user: fix 32bit g2h()/h2g()
sparc32plus has 64bit long type but only 32bit virtual address space.
For instance, "apt-get upgrade" failed because of a mmap()/msync()
sequence.
mmap() returned 0xff252000 but msync() used g2h(0xffffffffff252000)
to find the host address. The "(target_ulong)" in g2h() doesn't fix the
address because it is 64bit long.
This patch introduces an "abi_ptr" that is set to uint32_t
if the virtual address space is addressed using 32bit in the linux-user
case. It stays set to target_ulong with softmmu case.
