Vanessasaurus 4aeb0d19bd Singularity package: new version, legacy builds, and root permissions (#11094) ... * Remove old Singularity versions, add version 3.1.1 * Recent versions of Singularity build with go rather than autotools: update dependencies and build logic * Move old Singularity versions to new singularity-legacy package which uses the autotools build system * Some binaries built by Singularity need to be run as root: include a script that the user can run after the Spack Singularity install to change these permissions. * The Singularity go build expects to work with a custom stage directory relative to GOPATH: override the stage phase to create this expected path. * Update Singularity install config to point to Spack-installed makesquashfs dependency		2019-05-03 10:27:13 +09:00
