Subject: tools/virtio: compile with -pthread
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f03560a57c1f60db6ac23ffd9714e1c69e2f95c7;p=linux.git

tools/virtio: compile with -pthread

When using pthreads, one has to compile and link with -lpthread,
otherwise e.g. glibc is not guaranteed to be reentrant.

This replaces -lpthread.
