[FFmpeg-devel] [PATCH 2/3] tests/checkasm: Add partial support for wasm

[Zhao Zhili]

From: Zhao Zhili <zhilizhao at tencent.com>

WASI mssing signal and siglongjmp support. This patch workaround
build error and add simd128 flag. Please note that many tests use
large array on stack, so you need to increase the stack size when
build checkasm, e.g., --extra-ldflags='-Wl,-z,stack-size=10485760'
