glibc keeps sinf/sqrtf/floorf and the rest in libm, which macOS links implicitly; examples/lang/floats.ludic failed to link on the Linux build-and-test job. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# The headline guarantee of a self-hosted, C-free toolchain: assembled from the
|
|
# checked-in IR seed with clang alone, the compiler recompiles its own source
|
|
# and reproduces that seed **byte-for-byte**. A regression here (a compiler
|
|
# change that was never reseeded) is otherwise invisible until someone runs it
|
|
# locally. This job fails the moment out.ll != seed.ll.
