scripts/git-submodule.sh: Don't rely on non-POSIX 'read' behaviour
The POSIX definition of the 'read' utility requires that you specify the variable name to set; omitting the name and having it default to 'REPLY' is a bashism. If your system sh is dash, then it will print an error message during build: qemu/pc-bios/s390-ccw/../../scripts/git-submodule.sh: 106: read: arg count Specify the variable name explicitly.
