The file is distribution specific because it contains paths to headers and libs specific to the distribution. The clang/LLVM toolchain does not provide its own c stdlib so the paths must be supplied in some manner. In the current version of meson, v0.47.1, the only place where the paths can be specified is the cross-file. Other possibilities do not work: * setting CFLAGS, LDFLAGS only sets these for non-cross builds. * setting -Dc_args, -Dc_link_args on the command line also only sets these for non-cross builds. Support for specifying these for cross builds was added in v0.51.0 [0]. * the cross-file can't be split into generic clang cross config and distribution specific config. Support added in v0.52.0 [1].
