Description

Just happened in the test_install.sh check when building the 2.096.1 beta.

yum localinstall dmd-2.096.1~beta.1-0.fedora.x86_64.rpm --quiet --assumeyes
Error: 
 Problem: package dmd-2.096.1~beta.1-0.x86_64 requires libcurl(x86-32), but none of the providers can be installed
  - package libcurl-minimal-7.61.1-14.el8_3.1.x86_64 conflicts with libcurl provided by libcurl-7.61.1-14.el8_3.1.i686
  - package libcurl-minimal-7.61.1-14.el8_3.1.i686 conflicts with libcurl provided by libcurl-minimal-7.61.1-14.el8_3.1.x86_64
  - package libcurl-minimal-7.61.1-14.el8_3.1.x86_64 conflicts with libcurl provided by libcurl-minimal-7.61.1-14.el8_3.1.i686
  - problem with installed package libcurl-minimal-7.61.1-14.el8_3.1.x86_64
  - conflicting requests

Looking at issue 17647, I'd suggest to make those weak dependencies and then possibly research if sth. is left to be done for libcurl-minimal vs. libcurl.
