_AC_OUTPUT_LINKS

[Andreas Buening]

Hello!

Some time ago there was a discussion how to solve
ln -s ... || ln ... || AC_MSG_ERROR(...)
if neither "ln -s" nor ln works. I thought this had been
solved but it hadn't. Unfortunately, I don't remember
which solution has been finally proposed but it was
something with $as_ln_s.


A quick'n dirty workaround (also for autoconf 2.53a):
