dh_auto_configure: --disable-maintainer-mode

when building libcpuid ( https://notabug.org/themusicgod1/libcpuid/ ) dh_auto_configure tries to send in an option to configure "--disable-maintainer-mode". This is not recognized(anymore?).

debuild -us -uc -b
...
dh_auto_configure
 ./configure --build=x86_64-linux-gnu --prefix=/usr --includedir=\${prefix}/include --mandir=\${prefix}/share/man --infodir=\${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --disable-silent-rules --libdir=\${prefix}/lib/x86_64-linux-gnu --libexecdir=\${prefix}/lib/x86_64-linux-gnu --disable-maintainer-mode --disable-dependency-tracking
configure: WARNING: unrecognized options: --disable-maintainer-mode

removing --disable-maintainer-mode from

debhelper-11.3.2ubuntu1/lib/Debian/Debhelper/Buildsystem/autoconf.pm

and the corresponding test in debhelper-11.3.2ubuntu1/t/buildsystems/autoconf/configure
made debhelper no longer pass in the offending option, and the warning went away.
