Debian-based distributions allow you to install multiple versions of LLVM
in parallel, allowing you to access them individually using postfixed
`llvm-config` versions (ie `llvm-config-3.8` or `llvm-config-3.9`).
Ubuntu (Xenial) added packages for LLVM 4.0 with `-4.0` postfix (under
`llvm-4.0` package).
Crystal supports and uses 3.9 or 3.8, but no option for 4.0.
This change makes sure LLVM 4.0 is also tried first.
Before this change (with LLVM 4.0 installed):
$ make crystal
Using /usr/bin/llvm-config-3.8 [version=3.8.0]
...
$ bin/crystal --version
Using compiled compiler at `.build/crystal'
Crystal 0.23.0+177 [12ed6df] (2017-09-20)
LLVM: 3.8.0
Default target: x86_64-pc-linux-gnu
After this change (with LLVM 4.0 installed)
$ make crystal
Using /usr/bin/llvm-config-4.0 [version=4.0.0]
...
$ bin/crystal --version
Using compiled compiler at `.build/crystal'
Crystal 0.23.0+177 [12ed6df] (2017-09-20)
LLVM: 4.0.0
Default target: x86_64-pc-linux-gnu
