I have just tried compiling a simple program with #include
<stddef.h> then uses offsetof, and it compiles and runs fine both in
64 bits and 32 bits mode, so the multilib toolchain is fine.

I can only assume that something else in my setup is causing
pulseaudio to not include stddef.f for using offsetof.
