Wrong dependencies on linux-32

[wodudwodud]

I have linux-32 with miniconda2 installed.

Actual Behavior

I wanted to install scipy-1.1.0-py27hfa4b5c9_1. But I got:

PackagesNotFoundError: The following packages are not available from current channels:

• scipy==1.1.0=py27hfa4b5c9_1
• libgcc-ng[version='>=7.3.0']
• _libgcc_mutex=[build=main]

so , there is no _libgcc_mutex for linux-32 it is for linux-64.

Expected Behavior

To install without an error.

Steps to Reproduce

Anaconda or Miniconda version:

Operating System:

Linux Mint 19.1 32bit

This is a consequence of AnacondaRecipes/repodata-hotfixes#30, which in turn was meant to address conda/conda#8844 . The hotfix made libgcc-ng depend upon a new package _libgcc_mutex, but as conda is no longer supporting 32bit packages no version of _libgcc_mutex was produced.

In effect this cripples using conda for linux-32 - the hotfix changed dependencies for existing packages, so builds that worked prior to the fix are now broken. All of this would be resolved if conda produced a linux-32 build of the empty _libgcc_mutex package.

Sorry about this. Since we no longer but packages for Linux 32, this was an oversight. We will put up these packages soon.
