BZ #27: Building with CFLAGS set doesn't work

Status fields:

On builder.classpath.org we build all programs and libraries with CFLAGS set:
make CFLAGS=-g CPPFLAGS=-g CXXFLAGS=-g GCJFLAGS=-g $target

This doesn't work for cacao in the jit code:

 gcc -DHAVE_CONFIG_H -I. -I../../../../../cacao/src/vm/jit/i386 -I../../../..
-I../../../../../cacao/src -I../../../.. -I../../../../src -g -g -MT codegen.lo -MD
-MP -MF .deps/codegen.Tpo -c ../../../../../cacao/src/vm/jit/i386/codegen.c  -fPIC
-DPIC -o .libs/codegen.o

Fix commited.
