glib-2.2.3 build problem

[Ed Arnold <era ucar edu>]

I ran into a minor problem with build of glib-2.2.3 on a
sun-sparc-solaris2.9 system.  Can someone tell me if this is a bug
that should be reported, or a feature I should enjoy.

I run configure with only the --prefix flag.
After configure, config.log shows ENABLE_GTK_DOC_TRUE='#' has been set.
In the docs/reference/{glib,gobject}/Makefile.in files, substitution of
ENABLE_GTK_DOC_TRUE results in the "all-local" target being commented
out.  However, since the all-local target is in target lists for the
"all-am" and ".PHONY" targets, make spits out a fatal error because it
doesn't know how to make target "all-local".
