inetutils-1.4.1: unnecessary libraries linked on Linux

[Michael Deutschmann]

(This problem actually has existed for many versions).

On my GNU/Linux setup, the inetutils-1.4.1 build scheme links the libnsl,
libresolv and libz libraries into all applications.  It also includes
libm in ping.

None of those four libraries are actually needed for linking.  If I alter
ping's makefile to remove the "-lm", and build with "make LIBS=", it
compiles fine.

This is a mild annoyance for most of the inetutils programs.  But ping is
a special nuisance as it is customarily installed on the root partition.
I presently do not keep any of those four libraries in /lib, since no
other root-partition program requires them.
