I mean, a patch is needed only if one of the BR versions is less than a.b. So I
want to conditionally apply a patch, based on the version of the BR.
How about this evil untested recursive invocation of rpm?
%prep
%configure
package=glibc
minversion=2.13.89
if [ $(
rpm -q --queryformat '%{version}\n' $package |
cat - <(echo $minversion) |
sort -V |
head -1
) = "$minversion" ]; then
%patch0 -p1
fi
