Guilloux Stephan (Ubuntu) 91bc18ee16 Enriched Android helpers
2 more functions are added:
- android_clone_library():

  Similar to android_clone_library(), but fetch a tarball and uncompress it.

  So far, only .tar.gz and .tgz archives are supported, but could be enhanced
  easily, if needed.

- android_init_dependency_root():

  Initialize or check XXX_ROOT, when XXX is a dependency name.

  Enhanced version of init_android_root() in build.sh (to be dropped, then).
  This version is now also applicable in CZMQ & ZYRE CI builds scripts for Android.

#
# The following is a helper script for setting up android builds for
# "native" libraries maintained with an autotools build system.
# It merely helps to create the proper cross-compile environment.
# It makes no attempt to wrap the library or make it accessible to Java code;
# the intention is to make the bare library available to other "native" code.
#
# To get the latest version of this script, please download from:
# https://github.com/jemc/android_build_helper
#
# You are free to modify this script, but if you add improvements,
# please consider submitting a pull request to the aforementioned upstream
# repository for the benefit of other users.
