For Debian 7.0 (aka wheezy) packages it's recommended to use several
hardening flags, the default on amd64 being:
CFLAGS=-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security
CPPFLAGS=-D_FORTIFY_SOURCE=2
LDFLAGS=-Wl,-z,relro
This patch doesn't fix all warnings but at least makes all programs compile
again by not using char *variables as printf format strings.
