Because you requested an out-of-tree build, I guess. The vala build is
different enough that some assumptions in automake don't hold.

While this seems a bit weird (to touch the source dir for an out-of-tree
build), if automake devs are ok I think it won't hurt :-)

As I see it, if automake can generate a makefile that compiles the vala
code in the build dir, it would solve your build failure as well :-)

P.S. I don't know automake that well, I'm just a vala fanboy trying to
help :-)
