AndroidNdkGdb debugging macros broken

[ngaloppo]

I can't seem to get the debugging macros in AndroidNdkGdb working anymore. For one, it uses LIBRARY_OUTPUT_PATH, but that isn't being defined by the toolchain anymore (or I couldn't figure out how).

Also, when hardcoding the LIBRARY_OUTPUT_PATH, I ran into linking issues for executable targets depend on libraries that I have added with android_ndk_gdb_debuggable(libFoo). The linking stage fails due to missing symbols. It's almost like the stripping phase in AndroidNdkGdb has stripped the symbols out.

The problem seems to be that AndroidNdkGdb copies the original lib to obj/local, and then strips the symbols in the lib in libs/local. When making a change to a source file that is unrelated to the lib, the linking phase obviously fails because it's trying to link to a stripped version in libs/local.

Instead, the LIBRARY_OUTPUT_PATH should be set to obj/local (like ndk-build does) and then the install phase should copy / strip libs/local.

Please contribute if you are able to make a fix for AndroidNdkGdb. I personally have no plans for AndroidNdkGdb in any observable feature.
