qemu "make test" fails in iov.c with "undefined reference" on aarch64 on Ubuntu 16.04
I'm building the master tree on a multicore ARMv8 machine running Ubuntu 16.04. The build worked just fine, using the simple directions in the README file and "make -j 64" to do the build.
Next, I did "make test", and got this:
emv@armv8hello:~/src/qemu/qemu/build$ make test
make -C tests/tcg test
make[1]: Entering directory '/mnt/src/qemu/qemu/build/tests/tcg'
CC test_path.o
LINK test_path
test_path.o: In function `qemu_iovec_is_zero':
/home/emv/src/qemu/qemu/util/iov.c:365: undefined reference to `buffer_is_zero'
collect2: error: ld returned 1 exit status
/home/emv/src/qemu/qemu/rules.mak:105: recipe for target 'test_path' failed
make[1]: *** [test_path] Error 1
make[1]: Leaving directory '/mnt/src/qemu/qemu/build/tests/tcg'
Makefile:498: recipe for target 'test' failed
make: *** [test] Error 2
I expected "make test" to complete with no errors.
