rustc dependency on gcc-7 not required
On a new install of OI 2020.4 I installed rustc, then ran `cargo new foo`, then `cargo run foo`.
error: linker `/usr/gcc/7/bin/gcc` not found.
The same error occurs when directly invoking rustc.
I went to update the dependencies and submit a PR, but GCC seems to already be a dependency:
Maybe GCC_RUNTIME_PKG doesn't refer to the gcc binary itself but to the gcc libraries? Is there something simple I'm missing?
