Motiejus Jakštys b7da83e13e upgrade zig sdk
Also fix darwin zigtarget to none; see 5b813f1a2acdc1668e39008b02a234f3da724552 of zig

Motiejus Jakštys 4cfc30dd1c [fastbuild] use -fno-lto
This is very cache-unfriendly, because quite a lot of work is done
during the final linking stage. Let's see how this improves performance
of fastbuild.

laurynasl b73d167c6c Support bazel compilation_mode
Bazel has a special command line option (--compilation_mode) for specifying how
c artifacts should be compiled. Copy over the implementation without too much
thought on whether they make sense.

See https://docs.bazel.build/versions/main/user-manual.html#flag--compilation_mode.

!!! Due to a regression in zig-cc, debug symbols are available under --compilation_mode opt

```
laurynasl@laurynasl ~/bazel-zig-cc
 % bazel build -c opt //test/c:which_libc 2>/dev/null && bazel-bin/test/c/which_libc && gdb -batch --ex 'info line main' bazel-bin/test/c/which_libc
glibc_2.19
Line 4 of "test/c/main.c" starts at address 0x2014f0 <main> and ends at 0x2014f1 <main+1>.

Motiejus Jakštys 91ef17196b windows: add dynamic_library_linkopts
The patchset was created before
921fda9260, which added an option to
zig_cc_toolchain_config, causing a "soft merge conflict" after merging.

Jeremy Volkman 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.

Jeremy Volkman 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.

Motiejus Jakštys 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.

Motiejus Jakštys 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).

Ken Micklas fcb3d0432e Starlark's default argument semantics are pretty weird and likely not
what you would expect:

Additionally, this is just easier to read.
