# Wrapper that dispatches to `zig cc -target x86_64-linux-gnu.2.35`.
# Mirrors x86_64-linux-musl-gcc but pins a glibc 2.35 baseline; the
# resulting binaries run on any host with glibc >= 2.35.

# Intercepts `-print-prog-name=ld` and returns our cross-ld wrapper —
# libtool uses that query to discover the linker before probing it
# with `-m elf_x86_64` to decide whether shared library builds are
# supported. zig cc passes the query through to the host `/usr/bin/ld`,
# which is aarch64-only and rejects the x86_64 emulation mode, causing
# libtool to silently disable shared-lib emission. Pointing libtool at
# our ld.lld-backed wrapper makes the probe succeed.
