    samples/seccomp/Makefile: do not build tests if cross-compiling for MIPS · e9107f88
    Markos Chandras authored
    The Makefile is designed to use the host toolchain so it may be unsafe
    to build the tests if the kernel has been configured and built for
    another architecture.  This fixes a build problem when the kernel has
    been configured and built for the MIPS architecture but the host is not
    MIPS (cross-compiled).  The MIPS syscalls are only defined if one of the
    following is true:
     1) _MIPS_SIM == _MIPS_SIM_ABI64
     2) _MIPS_SIM == _MIPS_SIM_ABI32
     3) _MIPS_SIM == _MIPS_SIM_NABI32
    Of course, none of these make sense on a non-MIPS toolchain and the
    following build problem occurs when building on a non-MIPS host.
      linux/usr/include/linux/kexec.h:50: userspace cannot reference function or variable defined in the kernel
      samples/seccomp/bpf-direct.c: In function `emulator':
      samples/seccomp/bpf-direct.c:76:17: error: `__NR_write' undeclared (first use in this function)
