Thanks for reporting this.  Since your patch is against the gettext 
version of install-reloc, I am CC'ing this to bug-gnu-gettext.  I don't 
know why the two versions of install-reloc have diverged -- perhaps it's 
time to sync gettext back into gnulib?  But the problem should be fixed 
in the upstream version anyway.
