As far as I can see your error messages are complaining about missing 
functions that are called from the same sources as the functions that 
are missing! ie.

undefined reference to
`JvmtiEnvBase::get_current_contended_monitor(JavaThread*, JavaThread*,
_jobject**)'
/tmp/cc27HS5M.ltrans0.ltrans.o: In function `VM_GetOwnedMonitorInfo::doit()

but VM_GetOwnedMonitorInfo is defined in jvmtiEnv.cpp which should be 
included or excluded the same as jvmtiEnBase.cpp. Here's the logic in 
the makefile that controls this:

ifneq ($(call check-jvm-feature, jvmti), true)
   JVM_CFLAGS_FEATURES += -DINCLUDE_JVMTI=0
   JVM_EXCLUDE_FILES += jvmtiGetLoadedClasses.cpp jvmtiThreadState.cpp 
jvmtiExtensions.cpp \
       jvmtiImpl.cpp jvmtiManageCapabilities.cpp jvmtiRawMonitor.cpp 
jvmtiUtil.cpp jvmtiTrace.cpp \
       jvmtiCodeBlobEvents.cpp jvmtiEnv.cpp jvmtiRedefineClasses.cpp 
jvmtiEnvBase.cpp jvmtiEnvThreadState.cpp \
       jvmtiTagMap.cpp jvmtiEventController.cpp evmCompat.cpp 
jvmtiEnter.xsl jvmtiExport.cpp \
       jvmtiClassFileReconstituter.cpp
endif

Can you run with LOG=trace so that each compiled file is listed in the 
build log, then see if there are any jvmti* files listed there.

Thanks,
David
