Why not?
I refer to rare cases like this (.spec file excerpt):
Buildrequires: kdelibs-devel
%if %{!?_with_kde32:1}%{?_with_kde32:0}
%define have_mimetypedefs 1
%else
%define have_mimetypedefs %(if test -z $(rpm -ql kdelibs | grep -m1 x-iso.desk
top); then echo 0; else echo 1; fi)
%endif
This is no different from running Python or Perl code. If, however, you
mean "it is now permitted to do that although it works with plain
rpmbuild" (but breaks cross-platform build tools like mach), then that's
a different side of the story.
