[clang][Driver] Include stdc-predef.h by default on musl
Match GCC behavior for musl-based Linux targets by implicitly passing
`-include stdc-predef.h` for non-freestanding compilations.
Unlike glibc, musl does not arrange for this header to be included through
its normal system headers. As a result, Clang may miss predefined C macros
provided by musl's stdc-predef.h unless users include it manually, while the
same code works with GCC.
Add Driver tests covering musl, non-musl, freestanding, preprocessed input,
missing-header diagnostics, and actual macro visibility.
This patch is based on: https://reviews.llvm.org/D137043 and
slightly tweaks it, as the code has drifted since 2023 when
that was authored.

devel/ocaml-trie: New port
This OCaml library implements a trie tree in OCaml. A trie is a
datastructure used to implement a prefix search efficiently.

devel/ocaml-merlin: New port
Merlin assists you writing OCaml code by providing features commonly
found in integrated development environments (IDEs) such as code
completion, browsing, error reporting, etc. Integration with Emacs and
VIM are provided. Merlin is also a set of OCaml libraries to help one
implement said features.

devel/ocaml-magic-mime: New port
This OCaml library provides lookup functions to map a filename to a
MIME type (based on the extension of the file), and conversely from a
MIME type to a list of file extensions. As the database is bundled
inside an OCaml module, the lookups do not access the filesystem.

devel/ocaml-lwt_log: New port
Lwt_log is a logging library for OCaml applications using the Lwt
threading library.
WWW: https://github.com/ocsigen/lwt_log
devel/ocaml-js_of_ocaml-ocamlbuild: New port
This OCaml library provide a non-blocking interface to OpenSSL that is
compatible with application using the "lwt" cooperative threading
library.

devel/ocaml-gmap: New port
This library provides an hashmap implementation whose values are typed
by the type parameter of the associated (polymorphic) key. This
library relies on generalized algebraic data type (GADT) of OCaml.
WWW: https://github.com/hannesm/gmap
databases/ocaml-pgocaml: New port
This library implements the PostgreSQL wire protocol (version 2, for
PostgreSQL 7 and above) in pure OCaml. In addition to a low-level
interface, this library provides a PPX syntax extension to type-check
and validate SQL expressions at build time.
WWW: https://github.com/darioteixeira/pgocaml
devel/ocaml-duration: New port
Library to convert between various time units in OCaml. The underlying
representation uses nanoseconds on a 64 bits unsigned integer, for a
range of about 584 years.
WWW: https://github.com/hannesm/duration
devel/ocaml-integers: New port
This OCaml library provides 8-, 16-, 32- and 64-bytes signed and
unsigned integer types for OCaml. Additionally, platform dependent
types are provided, such as size_t, int, llong, etc.
WWW: https://github.com/yallop/ocaml-integers
converters/ocaml-hex: New port
A library for decoding and encoding base64 (RFC4648) strings in
OCaml. In addition to the default alphabet and an URI-safe alphabet
provided by this library, it is possible to use a custom alphabet.
WWW: https://github.com/mirage/ocaml-hex
devel/ocaml-ppx_optcomp: New port
Ppx_optcomp is an PPX OCaml syntax extention to introduce conditional
compilation in OCaml sources. It includes a simple expression language
to evaluate condition predicates.

security/ocaml-digestif: New port
Digestif is a hashing library for OCaml supporting the following
algorithm: BLAKE2B, BLAKE2S, Keccak-256, MD5, RIPEMD160, SHA1, SHA224,
SHA256, SHA3, SHA384, SHA512 and WHIRLPOOL.
This library permits to link against one of the two provided
implementations: the pure OCaml implementation ("digestif.ocaml"), or
one written in the C language ("digestif.c").

devel/ocaml-eqaf: New port
This OCaml library provides an equal function operating on strings in
constant-time. It may be used by cryptographic code to mitigate
timing-attacks.
