[PATCH] ARM: Do not select HAVE_RUST when KASAN is enabled

[Nathan Chancellor <nathan@kernel.org>]

When KASAN is enabled, such as with allmodconfig, the build fails when
building the Rust code with:

  error: kernel-address sanitizer is not supported for this target

  error: aborting due to 1 previous error

  make[4]: *** [rust/Makefile:654: rust/core.o] Error 1

The arm-unknown-linux-gnueabi target does not support KASAN, so avoid
saying Rust is supported when it is enabled.
