Using the epel-7-sclo-x86_64 chroot:

dev8 tools in CentOS 7
as shown below, the PATH must be changed to get the devtoolset-8 suite to work.

// resulting path from sclo-set.sh, shown below
<mock-chroot> sh-4.2# echo $PATH
/opt/rh/sclo-git212/root/usr/bin:/opt/rh/devtoolset-8/root/usr/bin:/usr/lib64/ccache:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin

// the dev8 loader is now first in the path and we have i386pep support
<mock-chroot> sh-4.2# ld -V
GNU ld version 2.30-55.el7.2
  Supported emulations:
   elf_x86_64
   elf32_x86_64
   elf_i386
   elf_iamcu
   i386linux
   elf_l1om
   elf_k1om
   i386pep
   i386pe

// each time mock is used, the path is set for dev8
<mock-chroot> sh-4.2# cat /etc/profile.d/sclo-set.sh
source scl_source enable devtoolset-8 sclo-git212

// efi support comes from binutils in dev8
