Build with more secure GCC flags

[DrWhax]

Hi,

I think it would be wise to use some more secure GCC flags to add an extra layer of security.

http://wiki.debian.org/Hardening

"-fstack-protector-all -D_FORTIFY_SOURCE=2 -O1 -Wl,-z,relro,-z,now -fPIE -pie"

When compiled, you could check with http://www.trapkit.de/tools/checksec.html if the GCC build is correctly build with the security GCC flags.

No idea on the performance impact, might be around 10/15% ..

Performance is critical to Redis. If you have a suggestion for specific flags, please include the performance impact.

Redis shouldn't run in unprotected networks, or have setuid set, as examples of why this doesn't have a high priority.

Closing this issue. Please feel free to reopen when you have more information. Thanks.
