Then I don't know why you get this error.  "It works for me" (TM).
Some Googling suggests that this might be a result of the missing
pkg-config package (see below).  If that doesn't help, maybe some
Autoconf expert could help you out.

Maybe there is, but I don't recommend that: configure scripts rely on
that package more and more as the time passes.  If you didn't have
that package until now, it means you couldn't build Emacs with librsvg
and GnuTLS.

That's a damn lie.  You need only Glib (and libintl+libiconv if you
don't already have them), in addition to pkg-config itself.

So, to summarize: install pkg-config and try again (starting with
running autogen.sh, I'd suggest, to countermand any problems you might
have caused by running without pkg-config).
