This is because systemtap stopped supporting the -fPIC option: libtool: compile: dtrace -G -s trace/generated-tracers.dtrace -fPIC -DPIC -o trace/.libs/generated-tracers.o /usr/bin/dtrace invalid option -fPIC This will not be needed anymore in QEMU 2.1.
Also reported https://sourceware.org/bugzilla/show_bug.cgi?id=17049
I'm backporting the libcacard patches that allow us to drop the offending dtrace invocation. So this will be fixed shortly
Fixed in qemu-2.0.0-7.fc21
