Re: [PATCH] Use xattr (Linux) in qcopy-acl.c

is needed when the user does

  ./configure --enable-xattr="no no"

In this case we don't want to see an error during configuration:

  checking for opendir... yes
  ../configure: line 29819: test: too many arguments
  checking for raise... yes

Always putting $use_attr in double-quotes achieves this.
