### ImageMagick version

7.1.1-4

### Operating system

Linux

### Operating system, version and so on

Debian 11 bullseye

### Description

Building from HEAD results in binaries without XML delegate built-in.  Using 7.1..0-62, it builds fine on the same system.

Trying to use it on a file with embedded XML results in the following error message:

`Exception 320: delegate library support not built-in ''PATH_TO_PNG_WITH_XML'' (XML) @ warning/profile.c/ValidateXMPProfile/1946 at … line …`

In both versions, `./configure` finds libxml2, configures --with-xml=yes, and sets CFLAGS and LIBS with xml:

> …
> checking for libxml-2.0 >= 2.0.0... yes
> …
> XML               --with-xml=yes		yes
> …
> CFLAGS          = -I/usr/include/libxml2 -I/usr/include/x86_64-linux-gnu -I/usr/include/libpng16  -I/usr/include/freetype2 -I/usr/include/libpng16  -fopenmp -Wall -g -O2 -mtune=haswell -fexceptions -pthread -DMAGICKCORE_HDRI_ENABLE=1 -DMAGICKCORE_QUANTUM_DEPTH=16
> …

However, the resulting build of 7.1.1-4 doesn't have the xml delegate:

While 7.1.0-62 does have the XML delegate:

### Steps to Reproduce

No XML delegate:
```
sudo apt install build-essential libfreetype6 libfreetype6-dev libpng-dev libjpeg-dev libtiff6 libtiff-dev libperl-dev ghostscript libltdl-dev pkg-config
git clone https://github.com/ImageMagick/ImageMagick.git
cd ImageMagick
./configure
make -j$(nproc)
./utilities/magick -version
# → Delegates (built-in): freetype jbig jng jpeg lzma png tiff zlib
```

Checking out 7.1.0-62 gets working XML delegate:
```
sudo apt install build-essential libfreetype6 libfreetype6-dev libpng-dev libjpeg-dev libtiff6 libtiff-dev libperl-dev ghostscript libltdl-dev pkg-config
git clone https://github.com/ImageMagick/ImageMagick.git
cd ImageMagick
git checkout 7.1.0-62
./configure
make -j$(nproc)
./utilities/magick -version
# → Delegates (built-in): freetype jbig jng jpeg lzma png tiff xml zlib
```
