I think what you want is

 z_HEADER_FILES_DIR = ../../x
 z_HEADER_FILES = a.h

or maybe

 z_HEADER_FILES_DIR = ../../
 z_HEADER_FILES = x/a.h

depending if you want the header installed as 

        z.framework/Versions/1.0.0/Headers/a.h

or as

        z.framework/Versions/1.0.0/Headers/x/a.h

If you need something even more complicated, there is also
z_HEADER_FILES_INSTALL_DIR to play with.

Thanks

PS: Using a file in a subdirectory (as in x/a.h) inside z_HEADER_FILES
is only supported since gnustep-make 2.4.0 (released May 2010).  If you
want to target older releases, avoid subdirectories in there, and use
z_HEADER_FILES_DIR and z_HEADER_FILES_INSTALL_DIR (if you can).
