--- Comment #3 from Brendan Batliner <bbatliner at ocient dot com> ---
Hi Florian, apologies for the late response, we de-prioritized
building on CentOS 8 for the time being.

Here are some steps to show you that CentOS 7's glibc-devel-2.17
package is built with 64-bit linker relocations. Output is edited
for brevity.

$ docker run -it --rm centos:7
[root@9bf6f62b0281 /]# cat /etc/system-release
CentOS Linux release 7.8.2003 (Core)
[root@9bf6f62b0281 /]# yum install -y glibc-devel
[root@9bf6f62b0281 /]# readelf -r /lib64/libc_nonshared.a | grep __dso_hand=
le
000000000003  000900000009 R_X86_64_GOTPCREL 0000000000000000 __dso_handle =
- 4
000000000003  000900000009 R_X86_64_GOTPCREL 0000000000000000 __dso_handle =
- 4
[root@9bf6f62b0281 /]# rpm -qf /lib64/libc_nonshared.a
glibc-devel-2.17-307.el7.1.x86_64


And here is the corresponding sequence of steps on the latest
CentOS 8 Docker image.

$ docker run -it --rm centos:8
[root@78d2c175012a /]# cat /etc/system-release
CentOS Linux release 8.1.1911 (Core)
[root@78d2c175012a /]# dnf install -y glibc-devel
[root@78d2c175012a /]# readelf -r /lib64/libc_nonshared.a | grep __dso_hand=
le
000000000007  003200000002 R_X86_64_PC32     0000000000000000 __dso_handle =
- 4
000000000007  003200000002 R_X86_64_PC32     0000000000000000 __dso_handle =
- 4
000000000007  003200000002 R_X86_64_PC32     0000000000000000 __dso_handle =
- 4
[root@78d2c175012a /]# rpm -qf /lib64/libc_nonshared.a
glibc-devel-2.28-101.el8.x86_64
