That would indeed cause the makefile to create a directory called  
"ppcjvm". And the compiler binary is always called "pp" and then  
renamed (moved) to "ppc<arch>", so that would indeed put the "pp"  
binary in that ppcjvm directory rather than renaming it to "ppcjvm".

Strange:

~/fpcjvm/rtl/java$ make FPC=ppcjvm2 OPT="-n -O2 -al" clean all
/bin/rm -f ../../rtl/units/jvm-java/system.ppu ../../rtl/units/jvm- 
java/uuchar.ppu ../../rtl/units/jvm-java/objpas.ppu ../../rtl/units/ 
jvm-java/jdk15.ppu
/bin/rm -f fpcmade.jvm-java Package.fpc ppas.sh script.res link.res
/bin/rm -f *.s *_ppas.bat
ppcjvm2 @rtl.cfg -Tjava -Pjvm -Fi../inc -Fi../jvm -FE. -FU../../rtl/ 
units/jvm-java -n -O2 -al -djvm  -Us -Sg system.pp

No, but maybe you did regenerate the makefile in rtl/java already with  
an fpcmake from trunk? The patch to prevent BINUTILSPREFIX being set  
in rtl/java/Makefile was applied in r18351
