This is not documented in the autoconf manual, section "Limitations of
Usual Tools". But I can confirm the fact:

$ { echo moon; echo light; } | /usr/ucb/tr -d '\n' ; echo
moo
light

$ { echo moon; echo light; } | /usr/bin/tr -d '\n' ; echo
moonlight
$ { echo moon; echo light; } | /usr/ucb/tr -d '\012' ; echo
moonlight
