a0511ca5ee Pass "-Wl,-undefined=dynamic_lookup" for dynamic libraries on darwin. 
This linker flag causes undefined symbols to be ignored, which is the
default behavior on linux but not macos. This is required when building
shared libraries to use as e.g. Python modules. This also matches what
Bazel's built-in macos cc toolchain does.

921fda9260 Adds dynamic_library_linkopts to zig_cc_toolchain_config 
If specified, the flags in dynamic_library_linkopts are included in
cpp_link_dynamic_library and cpp_link_nodeps_dynamic_library actions.

8fec0e3441 zig sdk: download from zig upstream as well as jakstys.lt 
Now that the toolchain supports multiple mirrors, we can have more
robust defaults: try ziglang.org first, then dl.jakstys.lt when that one
removes the build we rely on.

This will make builds less prone to inevitable failures of my home
server.

9ce21b5276 [zig ld] --gc-sections workaround + tests 
`zig cc` emits `--gc-sections` for the linker, which is incompatbile
with what CGo thinks about linking.

This commit adds a workaround: it will add `--no-gc-sections` to the
linking step if the command is not specified (falling back to the
default behavior of gcc/clang).

fcb3d0432e Starlark's default argument semantics are pretty weird and likely not 
what you would expect:
https://github.com/bazelbuild/starlark/blob/master/spec.md#functions

Additionally, this is just easier to read.
