bug#26797: qemu looks for smbd at /usr/sbin

[Ricardo Wurmus]

Qemu comes with support for sharing files with a guest via Samba.  This
is done by appending something like this to the qemu-system-*
invocation:

    … -net user,smb=$HOME/Downloads -net nic

Qemu needs to be told *at configure time* where the smbd executable will
be at runtime.  By default this is /usr/sbin/smbd.  Users can work
around this problem by installing the “samba” package and creating a
link from /usr/sbin/smbd to the actual executable.

It would be better to fix this, but this would require adding samba as a
dependency to Qemu, so that the location can be set at configure time.
Alternatively, we could patch Qemu to look for smbd depending on an
environment variable.
