[Nauty] broken --disable-static option

[Dima Pasechnik]

Hello,

trying to build nauty et al by running

./configure --disable-static && make

results in 

gcc -o dreadnaut -O4  -mpopcnt -march=native dreadnaut.c naututil.o \
	nautinv.o gtools.o traces.o nauty.o nautil.o nausparse.o naugraph.o schreier.o naurng.o

This is because all the .o files are placed in .libs/ if this option is
given, but rules to build executables such as dreadnaut are not adjusted
accoridingly.
IMHO in such a case one should link against the created dynamic
libraries.

Found while trying to update nauty package in Gentoo, one of Linux
distros:
