Emacs master build broken [GNU/Linux?]

[Angelo Graziosi]

At least on GNU/Linux Mint the build of Emacs from master is broken:


[...]
  CC       lastfile.o
image.c: In function ‘svg_load_image’:
image.c:12358:12: warning: implicit declaration of function 
‘rsvg_handle_get_pixbuf_and_error’; did you mean

*** You could try to:
*** - run "make bootstrap", which might fix the problem
*** - run "make V=1", which displays the full commands invoked by make,

I always do a clean build from 
https://git.savannah.gnu.org/cgit/emacs.git/snapshot/emacs-master.tar.gz.

Ciao,
