Can autotools Makefiles display commands they execute?

Question

I'm trying to build a project, at-spi2-core and I'm getting undefined references. Obviously, x11 libraries are not being linked. However, I'd love to see what command makefile actually outputs. Now the output is like so:

  CCLD     at-spi2-registryd

CCLD is not helpful at all. I've tried stuff in http://www.gnu.org/software/automake/manual/html_node/Debugging-Make-Rules.html but nothing seems to output how ld is being performed. This section happens in inner folder of registryd and not in a root (if that's of any relevance). Did anyone have similar problem with getting normal debugging output with autotools?

Normal makefiles always print out the commands they execute; CCLD and similar output are due to the Autotools "silent rules" feature. To disable it for one run of make, run make V=1 (V stands for Verbose). To disable it permanently, run configure again with --disable-silent-rules.

Can autotools Makefiles display commands they execute?
