Provide access to C compiler to crate build scripts. (#342)

Certain crates (e.g. openssl-sys, bzip2-sys) use "cc" during their
build script phase. Cargo just picks up "cc" available with CC env
variable or throught PATH.

This change exposes CC variable for build scripts with a path to
C compiler obtained from Bazel cc_toolchain.
