If you want to rebuild just the GC without optimization, just do (with 
an already built tree)

rm -rf build/i686-pc-linux-gnu/boehm-gc/
make CFLAGS=-g

(note that CFLAGS only affects C compilation, you also need to specify 
CXXFLAGS for C++ source files and GCJFLAGS for Java)

Alternativly you could "cd build/i686-pc-linux-gnu/boehm-gc/", change 
the value of CFLAGS in the generated makefile, and "make clean;; make"

By default the libgcj GC is currently not incremental. You can turn 
the incremental mode on, but it interacts badly with libjava's IO code 
(search the archives for the full story).
