Some people building QEMU use VPATH builds where the source directory is on a
read-only volume. In such a case 'scripts/git-submodules.sh update' will always
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 flag
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 arbitrary
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 what
todo. eg
$ ./configure --target-list=x86_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GIT submodule checkout is out of date. Please run
scripts/git-submodule.sh update ui/keycodemapdb

I'd love to see this warning when $GIT_UPDATE!=no too. Now it is:
GIT ui/keycodemapdb dtc
./scripts/git-submodule.sh: 36: ./scripts/git-submodule.sh: cannot create
.git-submodule-status: Read-only file system
Makefile:40: recipe for target 'git-submodule-update' failed
Other than that, looks nice, thanks for fixing it.

Oh sorry, I forgot that it was on-top of my previously sent patch:
