My bad... Here are the flags for this particular configuration
(prefix=$HOME/tmp/ok2delete):

 AUTOCONF_BUILD: x86_64-pc-linux-gnu
PKG_CONFIG_PATH: /home/jwalton/tmp/ok2delete/lib/pkgconfig
       CPPFLAGS: -I/home/jwalton/tmp/ok2delete/include -DNDEBUG
        ASFLAGS: -Wa,--noexecstack
         CFLAGS: -g2 -O2 -march=native -fPIC -pthread
       CXXFLAGS: -g2 -O2 -march=native -fPIC -pthread
        LDFLAGS: -L/home/jwalton/tmp/ok2delete/lib
-Wl,-R,'$ORIGIN/../lib' -Wl,-R,/home/jwalton/tmp/ok2delete/lib
-Wl,--enable-new-dtags -Wl,-z,relro -Wl,-z,now -Wl,-z,noexecstack
-Wl,-z,origin
         LDLIBS: -ldl -lpthread
