The following error hits if host cc compiler is clang(default one in most
linux distributions) and the cross compiler is gcc.
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.
