Specify -mcpu=cortex-a15 for denver CPU variants.

Extend the CPU ABI specification mechanism.

Add a (read only) system property that is a comma
separated list of ABIs supported by the device in order
of preference. For example, typical arm-v8 device might
define:

ro.cpu.abilist = arm64-v8a,armeabi-v7a,armeabi

For most purposes, a single flattened list like the above is
probably more useful than the parallel system of variables
TARGET_CPU_ABI{2} / TARGET_2ND_ARCH_CPU_ABI{2} that we use
in the build system.

Remove the unnecessary indirection of TARGET_STRIP_COMMAND

Now all archs use the same strip command which can be put just in
transform-to-stripped.

Fix java version detection when _JAVA_OPTIONS is set.

_JAVA_OPTIONS is an environment variable that
can be used to affect the behavior of java and javac.
It is currently required to get Android to build on
some configurations, where the default Java heap size
is too small. Unfortunately, if _JAVA_OPTIONS is set,
both java and javac will output its value to the console
as the first line on every invocation, including trivial
ones like java -version. This will confuse main.mk’s
version detection, which only looks at the first line of
output. Tweak the version detection to run grep before
head, so that the _JAVA_OPTIONS line is filtered by the grep.
