No, there is no problem with includes. The *dependencies* from t-*
files are missing.
Please compare i386.o dependencies from config/i386/t-i386 with
$(out_object_file) from the resulting Makefile in the build directory.
They are NOT the same, the dependencies in the Makefile from the build
directory for $(out_object_file) AKA i386.o are copied verbatim from
Makefile.in.

No, they are copied directly from Makefile.in.
