`configure_make()` and `meson()` don't work with hermetic toolchain

See #1295 for a reproduction example.

Both `configure()` and `meson()` don't seem to detect the hermetic toolchain and fail with errors like `C compiler cannot create executables`.

Start with the reproduction referenced in #1295, then inspect the configure() and meson() build-rule entry points for how they detect and invoke a hermetic toolchain. Reproduce the “C compiler cannot create executables” failure and use the existing behavior as the baseline for confirming the fix.
