It's normally in /usr/include/mach.h. Clearly, it's not going to be in
a x86_64-linux-gnu subdirectory, if anything, you want x86_64-gnu
(without the Linux part).

On Debian, it's in the libc0.3-dev package. The source file lives in
the glibc source tree and not that of gnumach, as Mikhail points out.
