Fix squid 3.0.13 cross compilation

Hi,

Here are some tiny patch to fix cross-compilation of squid 3.0.13. Here
host is x86_64-pc-linux-gnu and dest is i586-geode-linux-uclibc.

There is a first issue with cf_gen. cf_gen is generated with TARGETCXX
and should be build with HOSTCXX as it is used on runtime compilation.
squid-3.0.13-BJA-cf_gen-HOSTCXX.diff :

libtool: link: ( cd ".libs" && rm -f "libauth.la" && ln -s "../libauth.la" "libauth.la" )

I did patch src/Makefile.in which is not the perfect way to do that. I
failed to implement that in src/Makefile.am.

Then, I got many errors about xstr* which are not totaly cast
compliant. squid-3.0.13-BJA-util-cast-xstr.diff correct it :

You can see that correct HOSTCXX is used. But my HOSTCXX is gcc 4.3.3
which is a bit less compliant.

PS: Could you CC me it there is any reply as I'm not subscribe to the
list.

Thanks,
