Linux GCC toolchain

The files in this directory define how we build our GCC cross-compiler that targets Linux, using the musl libc.

A note about -rdynamic

Do not pass -rdynamic to GCC when building an executable; it will cause the compiled executable to depend on a musl libc dynamic loader in /lib that probably doesn't exist, and defeats the point of static linking. The -static option overrides -rdynamic, so adding-static to the linker flags of a project using -rdynamic is one way to fix the issue.

CMake will pass -rdynamic unless you set CMP0065 to new as shown below, or set your CMake policy version to 3.4 or later.

# Don't use -rdynamic since it causes Musl static linking to not work.
