- repair the xattr-gnulib-prepare patch to allow build tar without SELinux
support
- fedora-review compliance -> remove trailing white-spaces, remove macro from
comment, remove BR of gawk;coreutils;gzip that should be covered automatically
by minimum build environment, do not `rm -rf' buildroot at the beginning of
install phase (needed only in EPEL), remove BuildRoot definition, remove
defattr macro, s/define/global/
- do not use ${VAR} syntax for bash variables, use just $VAR
