Build fail - implicit declaration of function ‘vld1q_s8_x4’ on Armv7-linux with the latest release

[svilupp]

I wanted to build binaries for ARMv6,7 on Linux but I'm getting the following two errors:

[19:53:33] /workspace/srcdir/llama.cpp/ggml-quants.c: In function ‘ggml_vec_dot_iq2_xxs_q8_K’:

  | [19:53:33] /workspace/srcdir/llama.cpp/ggml-quants.c:7264:19: error: implicit declaration of function ‘vld1q_s8_x4’; did you mean ‘vld1q_s64’? [-Werror=implicit-function-declaration]
  | [19:53:33] 7264 | q8b = vld1q_s8_x4(q8); q8 += 64;
  | [19:53:33] | ^~~~~~~~~~~
  | [19:53:33] | vld1q_s64
  | [19:53:33] /workspace/srcdir/llama.cpp/ggml-quants.c:7264:19: error: incompatible types when assigning to type ‘int8x16x4_t’ from type ‘int’
  | [19:53:33] cc1: some warnings being treated as errors

They both seem to stem from the changes made in SOTA 2-bit PR.
I know that there was a reference that ARM NEON isn't supported yet, but I thought the above would still build.

I haven't found any way to build without the quants (eg, equivalent of the previous LLAMA_K_QUANTS=OFF).

Steps to reproduce:

cmake .. \
    -DCMAKE_INSTALL_PREFIX=$prefix \
    -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TARGET_TOOLCHAIN} \
    -DCMAKE_BUILD_TYPE=RELEASE \
    -DBUILD_SHARED_LIBS=ON \
    -DLLAMA_BUILD_TESTS=OFF \
    -DLLAMA_BUILD_EXAMPLES=ON \
    -DLLAMA_NATIVE=OFF \
    -DLLAMA_ACCELERATE=ON \
    -DLLAMA_AVX=ON \
    -DLLAMA_AVX2=ON \
    -DLLAMA_F16C=ON \
    -DLLAMA_FMA=ON \
    -DLLAMA_BLAS=OFF \
    -DLLAMA_CUBLAS=OFF \
    -DLLAMA_CLBLAST=OFF

Thank you for your advice!

PS: The error is similar to this one, but I don't believe it's related (different arch)
