bmk doesn't take configured options into account when preforming some actions

[woollybah]

Here, bmk is configured (via config.bmk) to use a specific compiler for the default target.

This result is different to the compiler it will build with (clang 17)

./bmk -v                        
bmk 3.57 mt-macos-osx-arm64 / clang 150000 / xcode 15.0.1 (cpu x10)

We may want to attempt to load the config file before we provide this information.
