Forcefully disable RVV intrinsics usage in llama.cpp/libggml.
The code assumes that if __riscv_v_intrinsic is defined the various RVV
intrinsics are available and usable.
With clang the intrinsics may be available even though actual usage of
said intrinsics has to be allowed with clang -march=... or function
annotations.
Also the code assumes that if it can use said intrinsics at compile
time then they ought to be used at runtime. This is false on
OpenBSD which doesn't require the cpu to support the V extension.
Example error at compile time:
.../firefox-154.0/third_party/llama.cpp/ggml/src/ggml-cpu/vec.cpp:407:22: error: RISC-V type 'vfloat32m2_t' (aka '__rvv_float32m2_t') requires the 'zve32f' extension
407 vfloat32m2_t vx = __riscv_vle32_v_f32m2(&x[i], vl);

fish/v3: fix build with libcxx22
libcxx22 uses [[__fallthrough__]] in a couple of headers, so redefining
__fallthrough__ to __attribute__((fallthrough)) yields a syntax error:
/usr/include/c++/v1/__functional/hash.h:70:24: error: expected expression
70 | [[__fallthrough__]];

Just don't do that...
Fix crash when trying to access the /admin/ page
Apparently checking passwords goes through checks for hash algorithms
supported by crypt(3). But since none of the algorithms checked are
supported by the OpenBSD libc, the code ends up dereferencing a NULL
pointer. I'm not sure yet why the code checks for algorithms supported
by crypt(3), as the code wasn't present in icecast-2.4.4.
To fix this, avoid dereferencing said NULL pointer. While here, add
DEBUG_PACKAGES.
