On the first "Configure" in a new build tree the cmake-gui pops up
a dialog to select settings for the toolchain to use.  That could
be taught to be sufficient for selecting such information prior
to the first configuration if it is not already.

The upstream Android NDK folks may be open to distributing files
that are CMake-aware with the NDK.  Then one could have a toolchain
file that does include(${ANDROID_NDK_ROOT}/.../toolchains.cmake)
to get information without scanning or globbing.  What kind of
info would NDK-provided files need to have to be most useful?
Or, perhaps the NDK could actually provide the toolchain files.
