Arch Linux

Description:
Submodules listed in PKGBUILD source array does not match submodules used during prepare and build

Additional info:
* python-pytorch 1.0.0-3
* https://bbs.archlinux.org/viewtopic.php?id=242636
* config and/or log files etc.


Steps to reproduce:
for top level sub modules
makepkg -odd then check for src/pytorch-1.0.0/.git/config for submodules using url's outside the src directory or not marked active
for nested sub module
extra-x86_64-build observe during build function

Submodule 'mkl-dnn' (https://github.com/01org/mkl-dnn.git) registered for path 'mkl-dnn'
Cloning into '/build/python-pytorch/src/pytorch-1.0.0/third_party/ideep/mkl-dnn'...
Submodule path 'mkl-dnn': checked out 'c0095ec26c215970b9b94915963b59e76398265e'
