- Use Autoconf macros to discover the correct target prefix for
`as`. Results are cached.
- Call `as` directly, bypassing the C compiler driver, on all
platforms that expose `as`.
- Allow using `llvm-ml`/`llvm-ml64` when building with clang-cl. Note
that LLVM 21 is required to assemble the current amd64nt.asm file.
- Remove the ASPP variable by imitating GNU Make implicit rules. Add
support for ASFLAGS.

Indication as to whether ocamlopt assembles files via the C compiler or by calling the assembler directly. Co-authored-by: Antonin Décimo <antonin@tarides.com>
mingw-w64 is based on GCC, so supports -fdebug-prefix-map, but the test for it is skipped in configure. The test is no longer skipped (which means that Config.c_has_debug_prefix_map returns true) but the flag is still explicitly not used by the compilers (as before).
