Makefile change in 7045397

[Jon Masamitsu]

This change to add free lists to the class metadata (part of the perm
gen removal project)

http://cr.openjdk.java.net/~jmasa/7045397/webrev.03/

has a change to make/excludeSrc.make to remove
freeList.cpp, binaryTreeDictionary.cpp, and
freeBlockDictionary.cpp from the exclude list.  These
files had code that was previously only used by the
CMS garbage collector but is now shared with
class metadata allocation code.  The
change also added adaptiveFreeList.cpp (code
specific to CMS removed from freeList.cpp) to
the exclude list.  The udiff for the change to
excludeSrc.make is

http://cr.openjdk.java.net/~jmasa/7045397/webrev.03/make/excludeSrc.make.udiff.html

This is a request to review the above change
to excludeSrc.make.

Thanks.
