This fixes the linker failing when:
- 32 bit libraries exist in "/usr/lib".
- 64 bit libraries are in "/usr/lib64" and not "/usr/lib/x86_64-linux-gnu".
vlib is the term for all modules included by default with V and
maintained as part of the V source code repository.
Some included modules depend on third party libraries, and these are kept
separate in the thirdparty directory at the root level of the source
repository.
