I'm doing incremental builds from make/sun/awt directory (this is on
windows-i586), and I have INCREMENTAL_BUILD set to 'true'.

When I touch some of the exported java files listed in
make/sun/awt/FILES_export_windows.gmk (for example,
src/windows/classes/sun/java2d/opengl/WGLGraphicsConfig.java),
javah is called twice, once for optimized build and once for debug build (actually, it's javah_g that's called the second time).

This slows down the build and doesn't seem to be necessary.
(I rebuild make/sun/awt/ a lot, and it adds up)

Also, if INCREMENTAL_BUILD is not set, then sometimes only javah_g is called,
meaning the opt. build doesn't call javah at all.
