ANDROID_BUILD_TOP variable is deprecated and thus all paths are assumed
to be relative to the top directory. However, this is causing problem
when some of the paths are constructed in the Android build system and
used in the non-Android makefiles that are usually executed NOT at the
top directory but at a sub directory using -C option. As a result, the
relative path from the Android build system become invalid in the
non-Android makefiles.
In order to overcome the restriction, ANDROID_BUILD_TOP is manually
constructed when invoking the non-Android makefiles by using $$(pwd).
The non-Android makefiles are expected to construct the absolute path
by prepending ANDROID_BUILD_TOP to any path that came from the Android
build system.

TARGET_TOOLS_PREFIX is a new variable introduced in build environment
which keeps the location of the toolchain from the android source, which
was working for 64bit but giving unwind warnings for 32 bit targets.

To solve this let's make the toolchain path prefix change in the target
BoardConfig file as per architecture(32/64) basis and avoid making change
in kernel.
