# executive environment.

#
# machine:
#
#   - can define ARCH variable (overriden by cmdline value)
#   - can define CROSS variable (overriden by cmdline value)
#   - define MACHINE_CFLAGS variable (overriden by cmdline value)
#   - define MACHINE_LDFLAGS variable (overriden by cmdline value)
#   - define MACHINE_ASFLAGS variable (overriden by cmdline value)
#   - can define CPU_CFLAGS variable (overriden by cmdline value) that
#     overrides the one defined in arch.
#   - can define CPU_LDFLAGS variable (overriden by cmdline value) that
#     overrides the one defined in arch.
#   - can define CPU_ASFLAGS variable (overriden by cmdline value) that
#     overrides the one defined in arch.
