Use flags of 24.0.0_pre20260725
- +clang Force building using installed clang (rather than the default CC/CXX; required for testing).
- +libcxxabi Build on top of llvm-runtimes/libcxxabi instead of gcc's libsupc++ (avoids depending on gcc).
- +static-libs Build static versions of dynamic libraries as well
- test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
