How about

 480 #  define xos_cpu_header(x, y)  XSTR(SUB(x)SUB(_)SUB(INCLUDE_SUFFIX_OS)SUB(_sparc)SUB(y))

-->

 480 #  define xos_cpu_header(x, y)  XSTR(CONCAT(x,_)CONCAT(INCLUDE_SUFFIX_OS,CONCAT(_sparc,y)))

or maybe even

 480 #  define xos_cpu_header(x, y)  CONCAT5(x,_,INCLUDE_SUFFIX_OS,_sparc,y)

I would have understood immediately what that was doing.

Andrew.
