Andreas Schneider 191e6b9441 waf: Build with RELRO if supported by the compiler.
Make sure we create binaries with full RELocation Read-Only support. See
https://isisblogs.poly.edu/2011/06/01/relro-relocation-read-only/
for more details.

The default is to check if the compiler supports RELRO and then enable
it. Specifying '--with-relro' will make it mandatory and
'--without-relro' will disable it.
