0.10.7 Build failed on FreeBSD

[hunreal at gmail.com (hshh)]

FreeBSD 10.1-RELEASE, ocserv-0.10.7

Making all in src
/bin/true
make[2]: exec(/bin/true) failed (No such file or directory)
*** Error code 1

There is no /bin/true on FreeBSD.
# which true
/usr/bin/true

For compile ocserv, I have to `ln -s /usr/bin/true /bin/true`.
I hope it can be fix next version.
