Yes. Actually, I'm using slightly different approach:

%build
# Fix includes so that local config header file will always supercede global options
for j in `ls *.c` ; do
    perl -pi -e "s/#include \"php.h\"/#include \"php.h\"\n#include \"config.h\"/" $j
done
phpize

%configure

BUILD_ENV_VARS="top_srcdir=$RPM_BUILD_DIR/%name-%version \
                bindir=$RPM_BUILD_ROOT/usr/bin \
                sbindir=$RPM_BUILD_ROOT/usr/sbin \
                includedir=$RPM_BUILD_ROOT/usr/include \
                exec_prefix=$RPM_BUILD_ROOT/usr \
                libdir=$RPM_BUILD_ROOT/usr/lib \
                prefix=$RPM_BUILD_ROOT/usr \
                localstatedir=$RPM_BUILD_ROOT/var/lib \
                PEAR_INSTALLDIR=$RPM_BUILD_ROOT/usr/lib/php \
                EXTENSION_DIR=$RPM_BUILD_ROOT/usr/lib/php/extensions"
make $BUILD_ENV_VARS
  
This is of course for RPM-based systems, but debian/rules will perform
with same success.
