Odd, I've done nothing in particular on FC5 and I got 

[pd at titmouse2 BUILD]$ grep -i java Makeconf
JAVA = /usr/bin/java
JAVA_HOME = /usr/lib/jvm/java-1.5.0-sun-1.5.0.06/jre
JAVA_LD_LIBRARY_PATH =
$(JAVA_HOME)/lib/i386/client:$(JAVA_HOME)/lib/i386:$(JAVA_HOME)/../lib/i386:/usr/local/lib
JAVA_LIBS = -L$(JAVA_HOME)/lib/i386/client -L$(JAVA_HOME)/lib/i386
-L$(JAVA_HOME)/../lib/i386 -L/usr/local/lib -ljvm
JAVAC = /usr/bin/javac

I suspect the installation of java was according to

http://www.fedorafaq.org/#java

and some of this has installed links from /usr/bin/javac to
/usr/lib/jvm/java-1.5.0-sun/bin/javac (via /etc/alternatives/javac)

Otherwise, there's always the option of actually reading the configure
script... I notice that it starts off looking for JAVA_HOME.
