Title: fix: gcc might not be the default c compiler

part3 of the patch series created in my sntp branch but are not necessary to enable the time sync feature

- ran into this one on a BSD system which only has clang installed for c compiler
- cc will always point to the c compiler.
- also since we build with cc, we should use cc while configuring too
