Multiple CI targets fail on rust-tree-sitter compile

[Rob Donnelly]

Relevant Error

cargo:warning=src/././atomic.h:25:29: error: '__ATOMIC_RELAXED' undeclared (first use in this function)

Cause

This is due to use of old GCC version without full C11 support specifically atomics.

The old GCC version is due to use of japaric/trust which uses rust-embedded/cross which provides Docker images that use an older version of Ubuntu (14.04). This is done to maximize the portablility of the generated binaries.
