Martin Stjernholm 4bbb9744db Use a better arbitrary target arch for this host-only "device". 
This "device" is used for linux_bionic builds that may build with
prebuilts (from prebuilts/runtime/mainline and prebuilts/module_sdk) on
master-art and master-art-host. The ndk arch suite was recently
extended to riscv64 (https://r.android.com/2488597), and those
prebuilts don't include that arch, which caused a failure in Soong
(even though target prebuilts aren't actually used here).

Test: lunch armv8-eng
      env DIST_DIR=out/dist ./art/tools/dist_linux_bionic.sh \
        -j80 com.android.art.host
  on master-art

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
