Fix Cross-compile Linking Args #26

Closed lenary closed 4 years ago

lenary commented 4 years ago

I was seeing some path resolution issues when using the clang cross file on a system that had a system install of the risc-v toolchain. Debugging this further, it seems like we need to pass these toolchain arguments down to <lang>_link_args as well as <lang>_args so that the clang driver picks up the right libraries to use.

Additionally, meson v0.53.1 introduced some per-language linker specification options, so I'm protecting us from getting bitten by that by explicitly setting those to the same as the ld option.

Verified on morty that these arguments now mean the clang driver finds the right libgcc to link to.
