Try something like this:

In ../Makefile.am:

BUILT_SOURCES = header.h
# build $(BUILT_SOURCES) before entering subdirs
Makefile: $(BUILT_SOURCES)

In ./Makefile.am:

../header.h: $(srcdir)/../header.h.in
        @( cd ..; $(MAKE) header.h )

The latter isn't necessary for ordinary builds, but if you change
header.h.in and start make from the subdir, you need the latter rule
to trigger the rebuild.
