Mihawk c0a75c51fa Flycast: Dreamcast, NAOMI, NAOMI 2 and Atomiswave, the sixteenth core ...

tools/build-flycast.sh builds Flycast's libretro core from my fork
../PS5_Flycast (b95c532f: upstream flyinghead/flycast 59ed35a7e plus five
commits) through tools/core-fork.sh, like the other forked cores:
- the PS5 libretro build: no --no-undefined, 16 KiB pages;
- the SH-4, ARM7 and AICA DSP recompilers' code in the console's executable
  memory (ps5_exec_allocate, near the core's code);
- anisotropic filtering takes the level chosen, not its index (upstream
  bug: "16" gave 4x, the default "4" gave 2x);
- PS5 defaults: 2880x2160, per-pixel transparency, 16x filtering; the
  widescreen hack stays off;
- no locale switching and no serial pseudo-terminal: the console exports
  neither uselocale/newlocale nor grantpt/unlockpt/ptsname, which the
  title's link refused.
The port began as rpf16rj's (pull request 3), credited in the fork's
commits; its networking (DCNet DNS and socket changes) and the
ps5_dc_rumble hook, which the title does not export, are left out.
tooling/flycast/ps5-toolchain.cmake is the cores' link contract with
libzip's Annex K and Windows probes answered no. The notices list Flycast
as GPL-2.0-or-later: its LICENSE is the GPLv2 text, and its file headers
say "version 2 or any later version", none "only". README: the system, its
resolution, the fork and the credit.

Verified on the base PS5 (13.40): runs 210509, 210719, 211230. The core
loads (core loader, Vulkan OIT renderer on RADV), Sonic Adventure (USA, Rev
A) boots through the HLE BIOS, plays its film, title screen and attract
demo at 2880x2160 with sound, and START reaches "Select a memory card";
RetroArch exits with 0 (evidence/flycast-sonic-adventure, pictures
klog/pad-210719 and klog/pad-211230). About 60 frames a second in the demo,
30 in the film (its own rate), early stalls of 0.5-1.4 s.
Gates: tools/verify.sh format, unit and evidence PASS (89 captures, 0
failed); build and integration wait for MAME's rebuild. Before a release:
publish github.com/mihawk-99/PS5_Flycast, which the notices and README name.
