That sed command comes from texi2pdf not gcc's makefile, so it must be a change
in texi2pdf
Try:
echo foo | sed "s/\(^\|.* \)@documenten/bar/"
In GNU's texi2pdf the corresponding rule is done differently, so you could try:
pgm='s/^ *@documentencoding *\([^ ][^ ]*\) *$/\1/
t found
d
:found
q'
echo foo | sed -e "$pgm"
