# AM_CHECK_ANDROID (ACTION_IF_FOUND, ACTION_IF_NOT_FOUND, [ACTION_IF_FAILED])
# enables the "--with-android" flag;
# if the androidSDK is detected, this will
# - set the CC & CPP to the cross-compiler ( resp preprocessor)
# - as well as the apropriate CFLAGS, INCLUDES and LDFLAGS
# - these values can also be found in ANDROID_CC, ANDROID_CPP,
# ANDROID_INCLUDES, ANDROID_ARCH, ANDROID_CFLAGS, ANDROID_LDFLAGS
# it will then call ACTION_IF_FOUND
# elif ACTION_IF_FAILED is set and the androidSDK is not detected even though the user
# requested it (by specifying a path, or simply saying "--with-android=yes"),
# then ACTION_IF_FAILED is called
# else
# ACTION_IF_NOT_FOUND is called
#
# TODO: only run checks when architecture is right (x-compiling)
# hc's code used "arm-linux"
