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.
