[boehm-gc] Fix libjava "PACKAGE_* redefined" errors

[Bryce McKinlay <mckinlay at redhat dot com>]

I'm checking in this patch to fix the redefinition errors that occur in 
the libjava build.

As far as I can tell libjava only requires one definition from boehm-gc, 
so I've moved only that one to gc_config.h and added a config.h.in to 
keep autoheader and gc.h happy.

Probably, we should also get rid of libjava's use of THREAD_LOCAL_ALLOC, 
and simply assume that its always on?

	Fix "PACKAGE_NAME redefined" errors.
	* configure.ac (AC_CONFIG_HEADERS): Build both include/config.h
	and include/gc_config.h.
	* include/gc_config.h.in: No longer auto-generated. Define only the
	macros needed by libjava.
	* include/config.h.in: Generated by autoheader.
	* include/gc.h: Include config.h, not gc_config.h.
