buildworld breaks while making texinfo

[Robert Huff]

	From the overnight build:

>  cc -O -pipe -DHAVE_CONFIG_H -DLOCALEDIR=\"/usr/share/locale\"  -I/usr/src/gnu/usr.bin/texinfo/makeinfo/../../../../contrib/texinfo -I/usr/src/gnu/usr.bin/texinfo/makeinfo/../../../../contrib/texinfo/lib  -I/usr/obj/usr/src/i386/legacy/usr/include -c /usr/src/contrib/texinfo/makeinfo/toc.c
>  cc -O -pipe -DHAVE_CONFIG_H -DLOCALEDIR=\"/usr/share/locale\"  -I/usr/src/gnu/usr.bin/texinfo/makeinfo/../../../../contrib/texinfo -I/usr/src/gnu/usr.bin/texinfo/makeinfo/../../../../contrib/texinfo/lib  -I/usr/obj/usr/src/i386/legacy/usr/include -c /usr/src/contrib/texinfo/makeinfo/xml.c
>  make: don't know how to make /usr/src/gnu/usr.bin/texinfo/makeinfo/../libtxi/libtxi.a. Stop
>  *** Error code 2
>  
>  Stop in /usr/src/gnu/usr.bin/texinfo.
>  *** Error code 1


	Have't changed anything (other than the source) in weeks.  Any
clues as to what's happened?
