Rework a problematic use of ${1+"$@"}

[Noah Misch]

Zsh performs field splitting on `${1+"$@"}'; m4sh mostly insulates us from this
fact with `alias -g '${1+"$@"}'='"$@"''.  However, this alias is not used if the
parameter expansion is part of a larger word, such as `"foo"${1+"$@"}'.  This
patches func_echo to avoid the problem, fixing quote.test on Mac OS X 10.1.

        * libltdl/config/general.m4sh (func_echo): Use $* instead of ${1+"$@"}.
