Are you using Automake, and if so, which version?  My recollection is that
older versions of automake often showed this behavior when a .m4 file that
was used in the previous build is deleted, because automake added it as a
dependency to drive an autoreconf, which then runs into the missing file.
I also recall that Ralf Wildenhues checked in a fix that lets newer
automake insert additional .PHONY designations to .m4 files, so that make
coupled with autoreconf can proceed after a renamed .m4 file (but I'm not
sure if it was automake 1.10.1, or the as-yet-unreleased 1.11).
