especially annoying ones are ones that %(execute) something.

therefore i've done over the time two kinds of optimizations in pld:
1. make such macros evaluate once:

# if %{_topdir}/SPECS exists, it's old style structure
%_specdir       %{expand:%%global _specdir %([ ! -d %{_topdir}/SPECS ] 
&& echo %{_topdir}/%{name} || echo %{_topdir}/SPECS)}
%_specdir
%_sourcedir     %{expand:%%global _sourcedir %([ ! -d %{_topdir}/SOURCES 
] && echo %{_specdir} || echo %{_topdir}/SOURCES)}%_sourcedir

2. in pld builder script, start with blank macros (skip our build 
macros), define ones used in .spec as %{nil} or () to leave syntax (but 
not values) valid

this at the time i made it, in php.spec optimized ./builder -bp from 3m 
to 3s
