bug#39727: statx error running 'guix gc' on CentOS 7

Hi Ludo,

Yes, all is good.  

I have re-built guix with your patch and started the daemon.  Now 'guix
gc' runs as expected:

.

.
deleted or invalidated more than 42 bytes; stopping
deleting `/gnu/store/trash'
deleting unused links...
note: currently hard linking saves 3264.68 MiB
guix gc: freed 0.91850 MiBs

Many thanks!  CentOS 7 will be around for a few years yet.

Best regards,

Paul.
