build.sh: simplify and semi-modernize 1. All POSIX shells support $(...) syntax [1], including /bin/sh. shellcheck warns about it. 2. [[ won't work in /bin/sh [2], so use [ everywhere. I wonder why it worked now, perhaps the test was running on a system where /bin/sh -> /bin/bash. 3. In POSIX sh, string indexing is undefined. [SC2039]. Unfortunately, this means we require a subprocess: https://wiki.ubuntu.com/DashAsBinSh. Very ugly. 4. In POSIX sh, arrays are undefined. We seem to use $flags as an array after constructing it by string concatenation. I tried to verify that this has the same effect as just passing the quoted string in bash: bash-3.2$ flags="-DCMAKE_GOOK" bash-3.2$ flags="$flags -DCMAKE_MOARMA" bash-3.2$ flags="$flags -DCMAKE_URURURUR" bash-3.2$ ./argv $flags 0: ./argv 1: -DCMAKE_GOOK 2: -DCMAKE_MOARMA 3: -DCMAKE_URURURUR bash-3.2$ ./argv "${flags[@]}" 0: ./argv 1: -DCMAKE_GOOK -DCMAKE_MOARMA -DCMAKE_URURURUR bash-3.2$ ./argv "$flags" 0: ./argv 1: -DCMAKE_GOOK -DCMAKE_MOARMA -DCMAKE_URURURUR bash-3.2$ 5. Enable exit on unknown variable (-u). All variables should be known, otherwise we have an error in the script. shellcheck doesn't warn so I think it's fine. Apart from shellcheck(1), I also ran checkbashisms(1). The latter only reported that "command -v" might not be available in other shells. Apparently only ash(1) doesn't understand it. NOTE: Why are we even trying to support pre-Mavericks (Darwin < 13) OSX? We don't even support the most modern OSX (El Capitan) fully yet. OSX upgrades are free and generally don't leave old machines behind. Most machines made after 2009 can upgrade to El Capitan, AFAIK. I also believe that systems that have all the utilities and libraries necessary to build PCSX2 will have /bin/bash >= 3.x. NOTE 2: Does cmake/ninja generate the same type of output in compile_commands.json?
