# AM_CHECK_IPHONE (ACTION_IF_FOUND, ACTION_IF_NOT_FOUND, [ACTION_IF_FAILED])
# enables the "--with-iphone" flag;
# if the iPhoneSDK 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 IPHONE_CC, IPHONE_CPP,
# IPHONE_INCLUDES, IPHONE_ARCH, IPHONE_CFLAGS, IPHONE_LDFLAGS
# it will then call ACTION_IF_FOUND
# elif ACTION_IF_FAILED is set and the iPhoneSDK is not detected even though the user
# requested it (by specifying a path, or simply saying "--with-iphone=yes"),
# then ACTION_IF_FAILED is called
# else
# ACTION_IF_NOT_FOUND is called
