When building with meson, the default size of virtual address space
reserved for mapping pages was globally set at 512GB, which is too big for
use in 32-bit processes. To match the behaviour with "make", we configure
this to be 512GB for 64-bit and 2MB for 32-bit builds.
Bugzilla ID: 498
Fixes: 66cc45e293ed ("mem: replace memseg with memseg lists")
