Current build instructions for iOS

Mon May 14 21:05:03 UTC 2018

I vaguely remember this being fixed in like jdk8u not too long ago. The 
ADLC build tool was not properly integrated to use the EXTRA_*FLAGS.

The simple solution is likely to add
ADLC_LDFLAGS += $(EXTRA_LDFLAGS)
somewhere just above the line
  $(eval $(call SetupNativeCompilation, BUILD_ADLC, \

In jdk/jdk, this is all rewritten and in much better shape.
