build: allow automatic git submodule updates to be disabled
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GEN trace/generated-helpers.h GEN trace/generated-helpers.c GEN module_block.h GIT submodule checkout is out of date.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 from the source directory checkout /home/berrange/src/virt/qemu make: *** [Makefile:31: git-submodule-update] Error 1 Tested-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.
