Add Android.mk support for building LLDB on Linux host.

This change adds support for building LLDB with the following
build command from the top level:

make FORCE_BUILD_LLVM_COMPONENTS=true ANDROID_BUILD_LLDB=true lldb

There are known issues with the google linux host gcc 4.6.2+ variant
currently used to build host executables.  A follow up change will
apply a temporary work-around that will be used until either the
compiler is fixed or a new compiler is used.
