Subject: [PATCH] build: set CMAKE_C_STANDARD to 99 for all dependencies

Older gcc versions (4.x) require passing --std=c99 compiler flag to
prevent warnings from being emitted. Instead of setting it for each
dependency, it's easier to just pass the CMAKE_C_STANDARD flag to all
dependencies. This also prevents the scenario of us forgetting to set it
if we add new dependencies.
