[Qemu-arm] [PATCH v2 25/28] Makefile.target: support per-target coverage reports

[Alex Bennée]

Add support for generating a single targets coverage report. Execute:

  make coverage-report

In the target build directory. This coverage report only cares about
target specific blobs so only searches the target build subdirectory.
