Bug #17491: `./configure' unsuccessful on Android NDK cross-build

We have no such command as getprop in our Android NDK cross-build environment, and so ./configure says

checking whether it is Android... yes
checking for Android API version... ./configure: line 9108: getprop: command not found

and finally dies saying

configure: error: size_t is signed

Currently, Ruby does not support Android officially. A patch is welcome.

I'm experimentally maintaining a CI on Android/Termux (http://rubyci.s3.amazonaws.com/android29-x86_64/ruby-master/recent.html), and it is only a test environment for Ruby with Android. Currently, no CI for cross-compilation is maintained unfortunately.
