That's not Linux, that's GNU libc plus the GCC compiler.

The problem will get worse when glibc gets more widespread.

stddef.h is a GCC header; it lives in the GCC include directory.

There's a magic way to get GCC to spit out the path to them:
"$(basename $(gcc --print-libgcc-file-name))/include"

That's the joy of working with the development version of Perl.  ;-)
