This is your bug-report: http://marc.info/?l=linux-kernel&m=140249607823283&w=2

+ make -s ARCH=x86_64
INSTALL_MOD_PATH=/home/jwboyer/rpmbuild/BUILDROOT/kernel-3.16.0-0.rc0.git1.1.fc21.x86_64
vdso_install KERNELRELEASE=3.16.0-0.rc0.git1.1.fc21.x86_64
make[1]: *** No rule to make target `arch/x86/vdso/vdso.so.dbg',
needed by `vdso.so'.  Stop.
make: *** [vdso_install] Error 2

I am building for i386 which is why I do not see the bug.
