build: prevent redefinition of _FORTIFY_SOURCE in gentoo
Add a -U_FORTIFY_SOURCE in HARDENING=1 [1] to prevent [2], e.g. as in:
x86_64-pc-linux-gnu-gcc -march=native -O2 -pipe -std=gnu99 -pipe -fPIE
-pie -Wl,-z,relro,-z,now -fstack-protector-all -Wstack-protector
--param=ssp-buffer-size=4 -ftrapv -D_FORTIFY_SOURCE=2 -fexceptions
-fomit-frame-pointer -fno-strict-aliasing -fasynchronous-unwind-tables
-fno-delete-null-pointer-checks -D_REENTRANT -D_LARGEFILE_SOURCE
-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -DVERSION_STRING=\""0.5.8-rc2"""\"
-DVERSION_LONG=\""0.5.8-rc2"" (Ziggomatic)"\" -DPREFIX_STRING=\"\"
-Wall -I. -I/usr/include/libnl3 -I/usr/include/libnl3
-DHAVE_DISSECTOR_PROTOS -DNEED_TCPDUMP_LIKE_FILTER -I/usr/include/libnl3
-I/usr/include/libnl3 -DHAVE_DISSECTOR_PROTOS -DNEED_TCPDUMP_LIKE_FILTER
-o netsniff-ng/proto_igmp.o -c proto_igmp.c
