assuming srcdir is sane, looks like it should work.  you should be able to 
test by doing:
# build in tree
        $ autoreconf -f -i
        $ rm -f libcpu/{i386,x86_64}_dis.h
        $ ./configure
        <make sure maintainer is enabled>
        $ make
        <should work>

# build a package
        $ make distcheck

# build out of tree
        $ make distclean
        $ mkdir build
        $ cd build
        $ ../configure
        <maintainer should not be enabled>
        $ make
        <should work>
