Additional cflags needed for aolserver4-* module compilation

[Malte Sussdorff]

Without additional CFLAGS "-W1,--no-as-needed" the compilation of aolserver4-nssha1 / aolserver4-nscache (and probably others) will return something like this when including the module in AOLServer as a loaded module

Warning: modload: could not find Ns_ModuleInit in /usr/local/aolserver/bin/nssha1.so

There are several threads that recommend to add -Wl,no-as-needed to the CFLAGS in each Modules Makefile, which is required. You can find more information e.g. at http://www.clever-devel.com/wiki/Warning%3a_modload%3a_could_not_find_Ns_ModuleInit_in_%2fusr%2flocal%2faolserver%2fbin%2fnssha1.so

The new source code versions of nssha1, nscache and nspostgres stored at https://github.com/cognovis/nssha1 https://github.com/cognovis/nscache and https://github.com/cognovis/nspostgres respectively have that already patched.

Without these changes using AOLserver on Ubuntu 14.04 is not possible and requires a manual compile (as detailed at http://erp4projects.de/install-project-open-on-ubuntu-14-4-lts/).

Thanks in advance for taking the time to provide new packages.
