Subject: [PATCH] add CFLAGS -mcmodel=medium for loongarch64 (#945)

The default code model of gcc for loongarch64 platform provides
256MiB PC-relative addressing space[1], which is not enough for
linking large binaries like chromium. Setting it to medium can
let libffi_pic.a get linked to large binaries successfully.
