The highest version of bash shipped by vanilla macOS is 3.2, and it will
stay like that for the foreseeable future (bash being removed as default
in 10.15 is a strong indicator for that).
The build.sh script used Bash 4.x syntax for enumerating available
translations - this patch dials back the clock to Bash 3.x making things
work again on macOS and (hopefully) still maintaining functionality on
other platforms that use a newer version of bash.
