Clang doesn't seem to have -fcheck-new, I tried to
add "BUILDLINK_TRANSFORM+=rm:-fcheck-new" to Makefile 
in the ".if !empty(PKGSRC_COMPILER:Mclang)" section.
Clang then finds a bug.
http://hg.openjdk.java.net/jdk8/tl/jdk/rev/eb441933f6fe
Adding these changes makes openjdk compile with Clang on my system.
NetBSD 6.1.2 clang 3.3 from pkgsrc 2013Q4.

You can try to do the same and see what result you get.
