[gdal-dev] Packaging linux/userfaultfd for conda

No idea. Anything that makes GDAL configure and then compilation happy should 
be good enough.

GDAL does the include this way:
#include <linux/userfaultfd.h>
so this should put in a linux subdirectory of a directory that GDAL will try 
to include. You just need the file for compilation. You don't need to 
distribute it as part of files installed by GDAL.

I wouldn't be super keen in providing system includes within GDAL, especially 
as this include file should be present on modern systems where the recent GDAL 
versions are more likely to be built.
