Use -D_FORTIFY_SOURCE=2 only if the gc optimization level is greater than 0.
Fixes Bug #7449: https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7449
-----
Issue:
Building Wireshark with '-O0 -D_FORTIFY_SOURCE=2 ...' fails
The warning [error] message:
/usr/include/features.h:314:4: error: #warning _FORTIFY_SOURCE requires
compiling with optimization (-O) [-Werror=cpp]`
A bit of research shows that this warning was added to a recent version of
glibc (on at least Fedora).
See: http://sourceware.org/bugzilla/show_bug.cgi?id=13979
The warning message occurs if -D_FORTIFY_SOURCE=... is used and the gcc
'optimization level' == 0 (-O0).
Unfortunately when building with -O0 this warning message:
1. Causes compiles to fail (if -Werror [stop on warning])
2. Causes ./configure to fail with an (incorrect) message
about the pcap header being older than the libpcap version.
