libtool: install: warning: relinking `libxcb-render.la'

libtool: install: error: relink `libxcb-render.la' with the above command before installing it
gmake[3]: *** [install-libLTLIBRARIES] Error 1
gmake[3]: Leaving directory `/var/tmp/libxcb-1.8/src'

This is what it does:
box1:/var/tmp/libxcb-1.8 root# cd src
box1:/var/tmp/libxcb-1.8/src root# cc -G -z defs -h libxcb-render.so.0 -o .libs/libxcb-render.so.0.0.0  .libs/render.o   -R/xcb/lib -R/usr/local/lib -L/usr/local/lib -L/xcb/lib -lxcb -lXau -lXdmcp -lsocket -lc

ld: fatal: Symbol referencing errors. No output written to .libs/libxcb-render.so.0.0.0

This is what it should do: (add .libs/xproto.o)
box1:/var/tmp/libxcb-1.8/src root# cc -G -z defs -h libxcb-render.so.0 -o .libs/libxcb-render.so.0.0.0 .libs/render.o .libs/xproto.o -R/xcb/lib -R/usr/local/lib -L/usr/local/lib -L/xcb/lib -lxcb -lXau -lXdmcp -lsocket -lc
box1:/var/tmp/libxcb-1.8/src root#

Doing the recipe with this step after the gmake patches the problem:
    gmake
    /bin/perl -pe "s%render.lo %render.lo xproto.lo %" -i src/libxcb-render.la
    gmake install

The build now completes.
