build: Allow building with OpenJDK v1.7

Ubuntu-12.10 ships with OpenJDK v1.7 and AOSP errors out if you try
to build it with JAVA version other than 1.6. Linaro Android build
with JAVA v1.7, boot tested on Origen 4412, seems to work fine.

Change-Id: I8ca783b48de80131f830139a33d8fc0aa92c562c
build: Add option to disable strict-aliasing optimizations

This is useful for builds that pull in unmodified AOSP repositories
that can't be compiled with strict-aliasing compliance enabled

in native-toolchain/Android.mk.

core: combo: use O3 for linker
ARM: add ARCH_ARM_HIGH_OPTIMIZATION
This enables -O3 instead of -O2 for thumb cflags intended for devices which don't have compatibility issues with -O3
everywhere.

build: Add support for TARGET_EXTRA_C{,PP}FLAGS

Add support for setting TARGET_EXTRA_C{,PP}FLAGS in board configs.
This can be used to set compiler flags for a board that break other
boards, such as -march=cortex-a9 or -DUSE_CUSTOM_EXTENSIONS_FOR_XYZ

definitions.mk: Don't fail if xmllint isn't installed

This is a workaround for xmllint currently not being installed on the
build slaves. It should be reverted when this is fixed, as it eliminates
a check for sane code.
