Elias Naur 10aede26d0 misc/android: fix detection of GOROOT tests 
strings.HasPrefix is not good enough to determine whether a path
is a subdirectory of another because it does not respect path
boundaries. filepath.Rel is good eonugh as long as we filter out results
that use parent directories, "..".

Hopefully fix the android emulator builders on the subrepositories.

Android
=======

For details on developing Go for Android, see the documentation in the
mobile subrepository:

	https://github.com/golang/mobile

To run the standard library tests, enable Cgo and use an appropriate
C compiler from the Android NDK. For example,

	CGO_ENABLED=1 \
	GOOS=android \
	GOARCH=arm64 \
	CC=$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang \
	./all.bash

To run tests on the Android device, add the bin directory to PATH so the
go tool can find the go_android_$GOARCH_exec wrapper generated by
make.bash. For example, to run the go1 benchmarks

	export PATH=$GOROOT/bin:$PATH
	cd $GOROOT/test/bench/go1/
	GOOS=android GOARCH=arm64 go test -bench=. -count=N -timeout=T
