apache rpm generation

Hi,

For the needed of our project, we have to compile our Apache as Platform Independent (i.e. with the -fPIE compile option and some other link options). 
We want to do the same with our freetds but there is now configure option that permit us to do that.
(because when we launch apache, we get a segfault and maybe this is because of enable-pie option)

Have you ever solve this issue?

Thanks,

A part of our spec file:
%build

#1 build of freetds
	cd $RPM_BUILD_DIR/%{FreetdsStem}
	./configure --prefix=%{ApacheFreeTdsRoot} \
	--enable-sybase-compat
	make clean
	make
	make install
	
#2 build of apache	
	cd $RPM_BUILD_DIR/%{ApacheStem}
	./configure --prefix=%{ApacheRoot} \
	    --with-included-apr \
		--enable-ssl \
		--enable-dbd \
	    --enable-mods-shared="dbd ssl" \
	    --enable-cache \
	    --enable-pie \
	    --enable-http \
		--with-freetds=%{ApacheFreeTdsRoot} \
		CPPFLAGS=-DAPU_DSO_BUILD=1
	make clean
	make
