For the record, it was another /bin/sh issue, fixed by 2365338.

Closing the bug now.  :-)

Looking at configure.ac, this is used to #define XKM_OUTPUT_DIR, which
ddxLoad.c describes like this:

--8<---------------cut here---------------start------------->8---
        /*
         * If XKM_OUTPUT_DIR specifies a path without a leading slash, it is
         * relative to the top-level XKB configuration directory.
         * Making the server write to a subdirectory of that directory
         * requires some work in the general case (install procedure
         * has to create links to /var or somesuch on many machines),
         * so we just compile into /usr/tmp for now.
         */
#ifndef XKM_OUTPUT_DIR
#define	XKM_OUTPUT_DIR	"compiled/"
#endif
--8<---------------cut here---------------end--------------->8---

I interpret it as /tmp being a good value.

At the same time, I wonder if the X server normally calls xkbcomp at
run time.

Thanks,
Ludo’.
