Here's a quick comment (or bug report) on one makefile, make/tools/freetypecheck/Makefile.

I'm trying out your patches on my macbook (Lion) with the late Xcode-supplied version of gcc.
  $ uname -a
  Darwin Sword2.local 11.3.0 Darwin Kernel Version 11.3.0: Thu Jan 12 18:47:41 PST 2012; root:xnu-1699.24.23~1/RELEASE_X86_64 x86_64
  $ /Developer/usr/bin/gcc --version
  i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)

That version of gcc fails to parse this command line from the jdk makefiles:
  $ /Developer/usr/bin/gcc … freetypecheck.c -L/usr/X11R6/lib -R /usr/X11R6/lib -lz -lfreetype

The error report indicates that the directory /usr/X11R6/lib gets treated as an ld input file:
  ld: in /usr/X11R6/lib, can't map file, errno=22 for architecture x86_64
  collect2: ld returned 1 exit status

By removing the space after "-R" in the makefile, I can pass the sanity checks and (apparently) build the real stuff:
  /Developer/usr/bin/gcc … freetypecheck.c -L/usr/X11R6/lib -R/usr/X11R6/lib -lz -lfreetype

Here is an updated diff hunk that works for me:

   else # other unix
+    ifeq ($(PLATFORM),macosx)
+      FT_LD_OPTIONS += -lz
+    endif
   FT_LD_OPTIONS += -lfreetype

Is this only a problem for people who make builds with OPENJDK=true?

After fixing the freetypecheck problem, my build completes fine.  This is the farthest I've seen a jdk8 build go on my mac in several weeks.  Thanks!
