sigrok-cross-android: Set CMAKE_MAKE_PROGRAM to fix libftdi build.

The libftdi build was failing (for quite a while now) like this:

  CMake Error: CMake was unable to find a build program corresponding
  to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need
  to select a different build tool.

Explicitly setting CMAKE_MAKE_PROGRAM seems to fix this.
