With this libxml2 update:
```
gm convert -list format
...
gm convert: Unable to load module ("/usr/lib64/GraphicsMagick-1.3.38/modules-Q16/coders/url.la: file not found")
```
In fact, `url.so` is there but cannot be dlopen'ed. This works after downgrading libxml2 to 2.9.
I noticed because my scribus failed to start today, and this was somehow tough to track down.
I still don't know whether libxml2 had an abi change without soname bump and whether a simple rebuild of GM would solve this (in particular, which one to file a big against). But since it was diificult to spot and more packages could be broken (without a clear FTI/FTBFS) I wanted to give a heads up here.
Confirmed, as I've noticed that now rubygem-rmagick is now FTBFS.
So I tried narrowing the issue and the minimum reproducer is:
$ ldd -r /usr/lib64/ImageMagick-6.9.12/modules-Q16/coders/url.so | grep undefined
undefined symbol: xmlNanoFTPInit, version LIBXML2_2.4.30 (/usr/lib64/ImageMagick-6.9.12/modules-Q16/coders/url.so)
undefined symbol: xmlNanoFTPClose, version LIBXML2_2.4.30 (/usr/lib64/ImageMagick-6.9.12/modules-Q16/coders/url.so)
undefined symbol: xmlNanoFTPGet, version LIBXML2_2.4.30 (/usr/lib64/ImageMagick-6.9.12/modules-Q16/coders/url.so)
undefined symbol: xmlNanoFTPNewCtxt, version LIBXML2_2.4.30 (/usr/lib64/ImageMagick-6.9.12/modules-Q16/coders/url.so)
undefined symbol: xmlNanoFTPConnect, version LIBXML2_2.4.30 (/usr/lib64/ImageMagick-6.9.12/modules-Q16/coders/url.so)
(i.e. ImageMagick is now broken)
This is perhaps due to the following change:
https://gitlab.gnome.org/GNOME/libxml2/-/commit/a0a0f3be93753e387e31e7de95904a24b3c876dd
... and in fact lots of other symbols are also removed...

I think libxml2 2.10.x (with current configuration) should not have brought into
F37/36/35 branches. Currently at least the following action is required.
* Either rebuilding all packages requiring the above symbol
* Or fixing libxml2 2.10.x
* Or introduce epoch on libxml2 and downgrade to 2.9.x

Mamoru
