RFR: 8145132: Initial updates for ios x86_64 mobile/dev builds.

[Bob Vandette]

1. In make/bsd/makefiles/vm.make

You commented out the libffi logic that we’ll need to Zero iOS ARM.  I guess we could uncomment this
with the push to add this support.

2. hotspot/src/share/vm/runtime/java.cpp

You shouldn’t need this change.  dll_lookup does the right thing
for static builds now.

661 #ifndef STATIC_BUILD

 662   void *lib_handle = os::native_java_library();

 663   func = CAST_TO_FN_PTR(jdk_version_info_fn_t,

 664      os::dll_lookup(lib_handle, "JDK_GetVersionInfo0"));

 665 #else
 666   extern jdk_version_info_fn_t  JDK_GetVersionInfo0;
 667   func = CAST_TO_FN_PTR(jdk_version_info_fn_t,
 668      &JDK_GetVersionInfo0);
 669 #endif


3. jdk/src/java.base/unix/native/libnio/ch/Net.c

Can you check to see that all of these changes are really necessary?

Bob.
