The GNU buildchain's "extern inline" support is disabled or broken
under Xcode.

One of "lisp-union.h" or "lisp-disunion.h" is included in about 80% of
source files, and there are dozens of such functions.  You're just
seeing the first clash for the first inline function declared.

For testing, you can probably get a build by adding

#define DONT_EXTERN_INLINE_HEADER_FUNCTIONS 1

at the top of $buildroot/src/config.h.  However, this will cause the
xemacs binary to bloat by some probably large amount because of the
duplicated function definitions in every file that includes "lisp.h"
(which is most of them).  If that doesn't work, then you can edit the
definition of INLINE_HEADER in that file to force inlines to be static.
