What's needed in rpm is a well defined, portable, and reasonably complete
set of tests and predictable name space, much like autoconf wrto config.status,
not more arcane --  compiled into rpm --  spec file syntax IMHO.

Here's a cheaper variant (entirely untested):

%{exapnd: %%define _libc_version %(<your test here>)}

%if %{_libc_version} = "2.2.2"	# <-- I think this works, maybe not
...
%endif

The %(<your test here>) could be as simple as
	%(rpm -q --qf '%%{version}' glibc)
on an rpm managed system.
