The root cause is: the hybride compilers add the warning options to the meson project as project arguments, which apply for both host compiling and cross compiling. But some options such as '-Wno-format-truncation' are not supported nor recognized by clang, so they have to be removed from the project arguments for the host compiler to run smoothily and added back as cflags for the cross compiler to compile for cross source files. The fix is remove unrecognized warning options from the meson project arguments shared by gcc and clang, as add them specifically for gcc or clang as cflags.
