In $QEMU_SRC/configure, architectures have these configuration options
(and several more):
    target_nptl="yes"
    target_phys_bits=32
    target_libs_softmmu="$fdt_libs"

In the target-*/cpu.h, there are defines like:

    #define TARGET_LONG_BITS 32
    #define TARGET_HAS_ICE 1
    #define TARGET_PAGE_BITS 12
    #define TARGET_PAGE_BITS 10
    #define TARGET_PHYS_ADDR_SPACE_BITS 40
    #define TARGET_VIRT_ADDR_SPACE_BITS 32

There are also required specification like CPUState or CPUArchState.

Is there any description of these configuration options?
