bug#26121: guile-2.2.0: date -d argument problem

[Thomas Klausner]

Hi!

When building guile-2.2.0 on NetBSD, I see:

gmake[2]: Entering directory '/scratch/lang/guile21/work/guile-2.2.0/libguile'
date: Expected digit in canonical time
date: -d
date: ^
Usage: date [-ajnu] [-d date] [-r seconds] [+format] 
[[[[[[CC]yy]mm]dd]HH]MM[.SS]]
  GEN      libpath.h
