a9a7490786 default-configs: use TARGET_ARCH key
Replace the individual TARGET_*=y lines with TARGET_ARCH,
similar to how TARGET_BASE_ARCH is handled already.

fdb75aeff7 configure: remove target configuration
The config-target.mak files are small constant, we can therefore just
write them down explicitly.

This removes a pretty large part of the configure script, including the
whole logic to detect which accelerators are supported by each target.
