BUILD_CFLAGS doesn't contain information about the recipe sysroot nor about the
target
system - and in case these are not specified for bindgen, then it builds against
the build system's headers, using the build system's arch.
Instead of BUILD_CFLAGS pass TOOLCHAIN_OPTIONS, which has the contains the
sysroot
already, and pass the target flag.
Fixes the following do_compile error:
| /usr/include/linux/types.h:5:10: fatal error: 'asm/types.h' file not found
