vulkan in termux

[liuw1535]

I am unable to use Vulkan on Snapdragon 870 Android devices. Here is my construction process:
Due to the lack of glslc, I deployed shaderc first, and the build command is:

cmake -GNinja \
-DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake \
-DANDROID_ABI=arm64-v8a \
-DANDROID_PLATFORM=android-24 \
-DSHADERC_SKIP_TESTS=ON \
..
ninja

Afterwards, copy the compiled glslc to/data/data/com. termux/files/usr/bin/
Now that glslc has been obtained, use the instructions in sd.cpp to build:

cmake .. -DSD_VULKAN=ON
cmake --build . --config Release

Finally, the SD binary file was obtained, but it cannot be used.

@liuw1535, hello, try latest master of ggml, I used ggml/475e012 commit, it seems to work. (Sort of 🙃, Vulkan version is 4 times slower than CPU for me, don't know why).
Though I built with Clang from Termux, not from NDK.
(And since I don't have Adreno, I used "vulkan-loader-android" package).

@liuw1535, out of curiosity, have you managed to run it? Maybe it also depends on version of "glslc" Vulkan compiler, I used this version of shaderc: google/shaderc@f5d626f .
