In such a case 'scripts/git-submodules.sh update' will al= ways fail and users are required to run it manually themselves on their original writable source directory. While this is already supported, it is nice to give users a command line fl= ag to configure to permanently disable automatic submodule updates, as it means they won't get hard to diagnose failures from git-submodules.sh at an arbit= rary later date. This patch thus introduces a flag '--disable-git-update' which will prevent 'make' from ever running 'scripts/git-submodules.sh update'. It will still = run the 'status' command to determine if a submodule update is needed, but when= it does this it'll simply stop and print a message instructing the developer w= hat todo. eg $ ./configure --target-list=3Dx86_64-softmmu --disable-git-update ...snip... $ make GEN config-host.h GEN trace/generated-tcg-tracers.h GEN trace/generated-helpers-wrappers.h GEN trace/generated-helpers.h GEN trace/generated-helpers.c GEN module_block.h GIT submodule checkout is out of date.

This is because config-host.mak contains a GIT_SUBMODULES variable that lis= ts a submodule that only exists in the later commit. config-host.mak won't get repopulated until config.status is invoked, but make won't get this far due= to the submodule error. This change makes 'git-submodule.sh' check whether each module is known to = git and drops any which are not present. A warning message will be printed when= any submodule is dropped in this manner.
