wip fix torchvision build

The build fails in a spectacular way with errors like the following:

In file included from /usr/include/glog/logging.h:77:
/usr/include/glog/log_severity.h:38:4: error: #error <glog/log_severity.h> was not included correctly. See the documention for how to consume the library.
   38 | #  error <glog/log_severity.h> was not included correctly. See the documention for how to consume the library.
      |    ^~~~~

There is:

• an upstream issue about this (https://github.com/pytorch/vision/issues/8307)

• A suggestion on the OOD of torchvision: From hot123tea123@gmail.com on 2024-02-26: https://github.com/pytorch/vision/releases/tag/v0.17.1

  if you fail to build this pkg with error logs like:

  #error <glog/logging.h> was not included correctly.

  you could try to define GLOG_USE_GLOG_EXPORT. see this PKGBUILD for example: https://github.com/archlinuxcn/repo/blob/19cea3cc03a87ddde65db8943212a7c2168a8b19/archlinuxcn/python-mmcv/PKGBUILD#L38

I've tried to get it to work, so far with no success 🤔
