Subject: [PATCH] meson: Remove check-compilation.sh

No need to involve a trivial shell script for this.

We could call the compiler directly, but test() expects arguments
to be passed separately and cc.cmd_array() can contain arguments
itself. Using env is easier than manually slicing the array because
meson has no builtins for that.
