libgnu.a is being built, it's not a dependency.  fcntl.o is what's
missing, it's supposed to be built from lib/fcntl.c.  I'm not sure why
make is skipping compilation (and for all the other C files in that
directory).  For reference, I excerpt what the build is supposed to look
below.  Which makes me notice the archlinux log doesn't seem to have the
"make[1]: Entering directory ..." part, perhaps that is significant?

make[1]: Entering directory `/tmp/emacs-master/lib'
  GEN      alloca.h
  ...
  GEN      time.h
  GEN      unistd.h
  CC       explicit_bzero.o
  CC       fcntl.o
  ...
  CC       save-cwd.o
  AR       libgnu.a
make[1]: Leaving directory `/tmp/emacs-master/lib'
