Are you using the normal Nmap makefile or something else? The build line
is very strange; it's compiling nping/nping.cc into nping/nping. Usually
our build enters the nping subdirectory and builds from there. The
undefined symbols that you are getting is because the link does not
include almost all of the object files needed. It's also using NMAP
defines instead of NPING defines.

Your build has this step:

g++ -g -O2 -Wall -fno-strict-aliasing   -I./liblinear -I./liblua -I./libdnet-stripped/include -I./libpcre  -I./libpcap 
-I./nbase -I./nsock/include -DHAVE_CONFIG_H -DNMAP_NAME=\"Nmap\" -DNMAP_URL=\"http://nmap.org\"; 
-DNMAP_PLATFORM=\"armv5tel-unknown-linux-gnueabi\" -DNMAPDATADIR=\"/usr/local/share/nmap\" -D_FORTIFY_SOURCE=2 -Wl,-E  
-Lnbase -Lnsock/src/    nping/nping.cc   -o nping/nping

When it really should be two steps like this:

g++ -c -I../libdnet-stripped/include  -I../nbase -I../nsock/include -g -O2 -Wall  -fno-strict-aliasing   
-DHAVE_CONFIG_H -DNPING_NAME=\"Nping\" -DNPING_URL=\"http://nmap.org/nping\"; 
-DNPING_PLATFORM=\"x86_64-unknown-linux-gnu\" -D_FORTIFY_SOURCE=2 nping.cc -o nping.o
g++   -o nping ArgParser.o common.o common_modified.o nping.o NpingOps.o utils.o utils_net.o output.o stats.o 
NpingTargets.o NpingTarget.o EchoHeader.o EchoServer.o EchoClient.o ProbeMode.o NEPContext.o Crypto.o PacketDiff.o  
../nbase/libnbase.a ../nsock/src/libnsock.a ../libnetutil/libnetutil.a -lssl -lcrypto -lpcap 
../libdnet-stripped/src/.libs/libdnet.a -ldl
