Changes to make gluegen build with NDK r7

- A bug in cpptasks was getting in the way of a working build with NDK
  r7. A local patch to cpptasks fixed the bug.
  - The patch is added as make/lib/cpptasks_gcclinker.patch and applies
    cleanly to cpptasts @ revision 177.
  - The result of building cpptasks r177 with this patch is part of the
    commit as well.
- Cleaned up and simplified the android cross-compile script in
  make/scripts.
- Cleaned up arguments passed to gcc for compiling and linking to look
  more like the command lines used for building NDK samples.
  - Some differences are necessary as cpptasks won't let us specify any
    binary other than 'gcc' for building. See
    gluegen-cpptasks-android-armv7.xml for comments on the matter.
- Thinking forward to x86 support, generalized jogamp-androidtasks.xml
  to install the gluegen shared library in a subdirectory of image/lib
  named for the targetted ABI for packaging with aapt. This file is
  no-longer ARM-specific.
