Merge remote-tracking branch 'pmaydell/configury.next' into staging

# By Paolo Bonzini (4) and others
# Via Peter Maydell
* pmaydell/configury.next:
  ppc: Remove CONFIG_FDT conditionals
  microblaze: Remove CONFIG_FDT conditionals
  arm: Remove CONFIG_FDT conditionals
  configure: Require libfdt for arm, ppc, microblaze softmmu targets
  configure: dtc: Probe for libfdt_env.h
  build: drop TARGET_TYPE
  main: use TARGET_ARCH only for the target-specific #define
  build: do not use TARGET_ARCH
  build: rename TARGET_ARCH2 to TARGET_NAME
  Add a stp file for usage from build directory
