I did some deeper research. The do_compile_prepend code from Koen(?) did not help here.

Makefile.am contains a target "noinst_PROGRAMS = strpool" which is used to create atasmart.strpool.c.

For the creation of this target strpool there are no special rules. Therefor it is build for the target (and overwrites the strpool built from do_compile_prepend) instead of the build host. :(

Is anybody able to write down a rule for strpool fixing this?
