ddidderr 079124511b build(fuzz): link migrated Rust archive into fuzz targets 
The fuzz Makefile compiles libzstd sources directly, so C compatibility shims
previously left migrated symbols unresolved.  Build and link a configuration
matched Cargo archive after the C objects for every fuzz target.

Track forced HUF mode changes with a C-object stamp to prevent a stale C
decoder from being mixed with another Rust archive.  A -m32 invocation now
also selects Cargo's i686 target rather than attempting to link native Rust
objects into a 32-bit fuzzer.

Test Plan:
- build and run huf_round_trip and dictionary_round_trip on LICENSE
- transition default to forced X1 and back without cleaning, then run input
- build and run huf_round_trip with C/C++/linker -m32 flags
- cargo clippy, cargo clippy --benches, cargo clippy --tests, and nightly fmt
