libadb.mk: modifications to make it build in yocto environment

Adding an include file that is setting the common flags.
Changed the cppflag to include the headers from other components
of android-tools

Modified LDflags so that the libraries that are coming from other android-tools
are searched in the output folder.

Modified the build rule so that it outputs the binary to the OUT_DIR
