Here is a patch to make tvm runtime working under FreeBSD. Compiling works ok
(including OpenCL) but runtime .py needs little adjustments to get the compiler
name and library search path. As a note simple .so (i.e. CPU only) compiled on
Linux work on FreeBSD ...

Subject: [PATCH] Updated runtime to run under FreeBSD - tested w/ 12.0,
g++9.

g++ is hardcoded in the current .py files. May be having the option to pass it
via environment or a different mechanism would be a good idea.
