Thanks for the pointers Noah, I was misreading the build log re "libgnu.a".


The weird part is that a previous(2019-Mar-24) emacs-git build, built
with the same PKGBUILD worked fine, found and built lib/fcntl.c.
- previous successful log build attached to this email

I've ran again, today, the build for emacs-git from the latest HEAD
(0c16bb5a39b38c48374bc3ad4ca99208ff329d46) and it fails in the same way,
it fails to find and build lib/fcntl.c, very weird.
