Пожалуйста:

%_variable_expand_list %nil
%set_variable_expand() %global _variable_expand_list %* ^
%add_variable_expand() %global _variable_expand_list %_variable_expand_list %* ^
%___pre_variable_extender() %{expand:%(echo %_variable_expand_list | \
		while read -d^ var1 var2 ; do \
			echo -e "\\tunset $var2 ||:\\\\" ; \
			echo -e "\\t%%{?$var1:export $var2=\\\"%$var1\\\"}\\\\"\
		done \
		)}

Результат работы:

$ rpm -v --define '__ccache_use 1' --define '__ccache_dir /foo/bar' --eval '
%add_variable_expand __ccache_use GCC_USE_CCACHE
%add_variable_expand __ccache_dir CCACHE_DIR
%add_variable_expand __ccache_false GCC_FALSE_CCACHE
%___pre_variable_extender'

         unset GCC_USE_CCACHE ||:\
         export GCC_USE_CCACHE="1"\
         unset CCACHE_DIR ||:\
         export CCACHE_DIR="/foo/bar"\
         unset GCC_FALSE_CCACHE ||:\
