The idea is "target" as opposed to "host".

Because that's what default-configs/ is for---producing
config-devices.mak. IOW it's mostly to reduce the scope, but also
because there are differences between config-devices.mak (produced from
default-configs/) and config-{host,target}.h (produced by configure).
In particular, config-host.h and config-target.h are header files, but
config-devices.mak is not because the same file is linked into multiple
QEMU binaries that can and will enable different devices. The only way
to use a hypothetical config-devices.h would be to move its users from
common-obj-y to obj-y.
