b2's clang.jam init-flags-cross generates --target=x86_64-pc-linux, which doesn't match clang's per-target runtime directory layout (x86_64-unknown-linux-gnu). This breaks any b2 link needing the sanitizer runtime, including ac library detection for zlib/bzip2. Vendor the Boost 1.88.0 CCI recipe with two changes: - Require b2 >= 5.4 which includes <triple> support (bfgroup/b2#466: allow explicit target triple for clang-linux and clang-darwin) - Set <triple>none in user-config.jam for clang to disable b2's target guessing, letting clang use its own default triple This replaces the profile workaround that cleared sanitizer flags for the Boost build. Boost is now built with full ASAN/UBSAN instrumentation. See bfgroup/b2#584

Proposed changes
Add an option to
clang-linuxandclang-darwintoolset modules that allows setting the target triple flag (--target=) explicitly rather than guessing it from the build requirements. Fix #449.I didn't add anything to the other
clang-modules as they do not pass the--targetflag.Types of changes
