I also believe this in gnattools/Makefile (generated) to be wrong:

# For cross builds of gnattools,
# put the host RTS dir first in the PATH to hide the default runtime
# files that are among the sources
# FIXME: This should be done in configure.
RTS_DIR:=$(strip $(subst \,/,$(shell gnatls -v | grep adalib )))
gnattools-cross: $(GCC_DIR)/stamp-tools

See how it calls gnatls to find out the path to adalib, even though
it’s cross-compiling? From amd64 to m68k (LP64 → ILP32), this produces
errors later on; changing gnatls to m68k-linux-gnu-gnatls fixes them.
