Currently, CFLAGS and CXXFLAGS are not making it into the compile line. This is because meson appends CFLAGS/CXXFLAGS from the environment only for native but not for cross builds (probably to keep cross-builds more isolated). As a result, we need to make sure these vars goes into meson.cross. This is similar to what cmake.bbclass does with OECMAKE_C_FLAGS and OECMAKE_CXX_FLAGS. Change c_args and cpp_args in meson.cross to include these vars, and update write_config[vardeps] accordingly.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
