#6 Does not configure with ash shell

[Sam Couter]

The configure script generated by autoconf for NJAMD
will not run correctly when /bin/sh is a symlink to the
ash shell.
More specifically, when more than one command is
concatenated on the one line (such as AC_MSG_RESULT and
AC_DEFINE), screwyness results. Keep your commands on
seperate lines.
I do not know what is correct POSIX behaviour in this case.

Trivial patch to fix the problem
