Patch taken from Debian sid.  Adapted to 4.2.4.6 for Guix by Tobias
Geerinckx-Rice <me@tobias.gr>.

Description: Support uncompressing and compressing soft links.
 Historically, ncompress for Debian has been built using a command line
 directly in debian/rules.  For 4.2.4.5-1, I simplified by swtching to the
 upstream Makefile.  However, that caused a regression - the Debian version of
 ncompress has always successfully handled soft links, but this stopped
 working.  To revert to the original behavior, I need to remove -DLSTAT from
 the build options, to be consistent with how the code was previously built.
