Subject: [PATCH] tests/docker: add flex and bison to emsdk-wasm64-cross
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The hexagon idef-parser requires flex and bison as host build
tools.  Add them to the emsdk-wasm64-cross container image so that
wasm64 builds including hexagon-softmmu can find them.
