Use -target-feature for MTE

Instead of setting -march, use clang's -target-feature functionality
to enable MTE. Some projects set -march which may conflict with MTE's
usage. Using -target-feature to enable MTE removes any clang command
line ordering issues.

History:
* Originally submitted as 3340cf27f76a94b1536e66e5847b11e334c97b85
* reverted in 32721f125b1ed0db3fbd434c2412dcf1f1e146e9 due to
  bug 371029823
* Prematurely resubmitted as fe67d8f1f22106bcc6634652ea1a5303e406f639
  and then subsequently reverted in
  476da833e12179d31f6a301ad65bf45c63a28818 as the fix for bug 371029823
  had not yet landed.
* Reapplied as f2c78addd495210722e8138c67444dd5419e9b7b and
  subsequently reverted in f274f7cd26901b89d2b141c0df89e4a443e761ba
  due to bug 399925046 (build timeout issue), which was resolved in
  bug 401292715 (re-client upgrade).

Let's try again. 4th time's the charm.

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For an outdated reference on Android.mk files, see build-system.html.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.
