You can use the same approach we used previously for other macros, e.g.

%{?!gem_install: %global %gem_install(d:n:) \
mkdir -p %{-d*}%{!?-d:.%{gem_dir}} \
\
CONFIGURE_ARGS="--with-cflags='%{optflags}' $CONFIGURE_ARGS" \\\
gem install \\\
         -V \\\
         --local \\\
         --install-dir %{-d*}%{!?-d:.%{gem_dir}} \\\
         --bindir .%{_bindir} \\\
         --force \\\
         --document=ri,rdoc \\\
         %{-n*}%{!?-n:%{gem_name}-%{version}.gem} \
%{nil}
}

Or some simplified version. Please note that I did not tested this 
macro, so I am pretty sure it does not work out of the box ;) Of course 
if you can express your voice in this ticket [3], that wold be best :)

Good catch. Thank you for pointing out. It is just in draft [1]. 
Although it was approved [2] (with some comments), it is not propagated 
into main guidelines page :/
