That looks great, thank you!
I haven't found a good solution to systematically test for target because running target binaries is not ideal (exec and target can be different).
Indeed. But, target settings are covered in detail by the analysis tests, so, I think we have good enough coverage.

This PR brings a "host_" counterpart to all
//zig/settingsbuild flags.Motivation
Allow having different settings for exec vs target configuration like compiling tools in debug and target binaries in release_fast (host_mode=debug, mode=release_fast)
How
Duplicate all settings with a
host_variant and populate theZigSettingsInfoprovider with either of the normal orhost_variant build setting value depending on whether we are building for tool (-exec in gendir hack).Test
Testing for exec is easy because the existing tests were build
for tooland execed byrun.I haven't found a good solution to systematically test for target because running target binaries is not ideal (exec and target can be different).
