Build fails on Linux with clang

Hi,

I built dav1d successed on Linux x86-64 machine, and run build/tools/dav1d successed.

But I need to build dav1d for Android, so I build davld with cross-file, and using clang , I had try clang version 6/7/8, it is all the same.

The compilation command is as follows:

meson build --buildtype release --cross-file cross-cfg.ini

ninja -C build

Ninja built failure in compiling .s file, please help check the following error log:

[43/92] Compiling C object 'src/25a6634@@dav1d@sha/arm_32_looprestoration.S.o'.
