There is no code trying to include the header, GCC doesn't include it
directly, it is included by glibc's <features.h> which is included by
other headers GCC uses.

The point is, how do you test for "the needed 32 bit dev package"?
The only way is to try compiling a program as 32-bit, but that can
only be done by the target compiler once it's built, because the host
compiler might not be capable of 32-bit output.
