That <FLAGS> is implicitly the flags for the corresponding language
since it appears in the compilation rule specific to the language.

For the Makefile generator take a look at
cmMakefileTargetGenerator::WriteTargetLanguageFlags
cmMakefileTargetGenerator::WriteObjectBuildFile
methods. They generate a <LANG>_FLAGS variable in the makefile and
reference it. Make sure those code paths are executed for Swift.
There should be similar code for the Ninja generator too.
