Cross Tier 1

run.sh is the Tier 1 cross-compile/link sentinel. It covers the portability support set at build/link depth only; it does not execute target artifacts.

Missing provisioned sysroots or SDKs are reported as SKIP and fail the run by default. Real compile/link failures are FAIL. Narrow local runs with T1_CROSS_TARGETS=<selector> when you only intend to cover one slice; use KIT_TEST_ALLOW_SKIP=1 only when you explicitly want a permissive probe.

Covered lanes:

• linux-{glibc,musl}-{aa64,x64,rv64}; musl runs both static and dynamic link modes.
• freebsd-{aa64,x64,rv64}.
• windows-{aa64,x64}.
• android-aa64 as a shared NativeActivity build.
• macos-{aa64,x64} when the macOS SDK is available on Darwin.
• ios-aa64, ios-sim-{aa64,x64} when the relevant Xcode SDK is available.
• freestanding-{aa64,x64,rv64,rv32,arm32} with compile plus kit ld.

Provision hosted sysroots with:

make provision TARGET=<selector>
