Makefile: revisit/improve checkprefix handling (#10348)

Browse Source 
Main improvement: do not error out, but re-run CMake in case
CMAKE_INSTALL_PREFIX changed, and only check it for "install".

- only look at CMAKE_EXTRA_FLAGS via shell if not empty
- add CMAKE_INSTALL_PREFIX to CMAKE_EXTRA_FLAGS (not CMAKE_FLAGS), to
  override it being set in CMAKE_EXTRA_FLAGS from local.mk
- use an empty "checkprefix" target if CMAKE_INSTALL_PREFIX is not
  provided
- skip checking of cached value without build/.ran-cmake; it will be run
  then anyway
- only use it with "install" target; it is only relevant there
- do not error, but re-run CMake (by removing the stamp file)
