run-generator jobj build step not processing symbolic links to jawt.h

[Stephen Bannasch]

I'm still getting errors executing the run-generator part of jobc because the build script is not able to process symbolic 
links properly -- the run-generator loads jawt_md.h but can't resolve the reference to jawt.h:

/System/Library/Frameworks/JavaVM.framework/Headers/jawt_md.h:10:18: error: jawt.h: No such file or directory

The full console output from the build starting with successfully running: build-core-native and build-generator and then 
showing the error while executing run-generator is here:

https://gist.github.com/901960

I can cat both header files successfully:

   /System/Library/Frameworks/JavaVM.framework/Headers/jawt_md.h
   /System/Library/Frameworks/JavaVM.framework/Headers/jawt.h

Both are symbolic links to:

   ../../CurrentJDK/Headers/jawt_md.h
   ../../CurrentJDK/Headers/jawt.h

I've expanded some of the initial console run-generator output below to show the classpaths more clearly:

I'm starting the build with this line:

unset LC_ALL LANG CLASSPATH JAVA_HOME LD_LIBRARY_PATH; make ALLOW_DOWNLOADS=true SA_APPLE_BOOT_JAVA=true 
ALWAYS_PASS_TEST_GAMMA=true ALT_BOOTDIR=`/usr/libexec/java_home -v 1.6`

The ALT_BOOTDIR is being set to:

   /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

I'm using MacOS X 10.6.7, xcode 3.2.6 and java 1.6.0_24
