When libelf is disabled in the configuration, we get the following
linker error:
LINK libperf-jvmti.so
ld: cannot find -lelf
Makefile.perf:515: recipe for target 'libperf-jvmti.so' failed
This patch fixes the error by using the configuration macro EXTLIBS.
Fixes: d4dfdf00d43e ("perf jvmti: Plug compilation into perf build")
