dmd version v2.089.0 should work for you, and you can use that to build a newer version of dmd. You can get it from http://downloads.dlang.org/releases/2019/
You can use this on an older Linux system to generate more compatible binaries, or you can try building static binaries. I've got a short guide for LDC on Alpine Linux in a docker container at https://d.minimaltype.com/index.cgi/wiki?name=statically-linked+binaries
>Is it possible to build the compiler and the tools with more "backward compatible" glibc version numers like memcpy@GLIBC_2.2.5 and fcntl@GLIBC_2.2.5? IIRC this is accomplished by using
asm (".symver memcpy, memcpy@GLIBC_2.2.5");
asm (".symver fcntl, fcntl@GLIBC_2.2.5");
in the source code.
... I'd hope that the version numbers aren't so meaningless that dmd could get away with just lying about them and not have horrible problems.
I'd prefer that dmd work out of the box on old Linux systems too, but you're probably past EOL in other big ways as well, there. A stock CentOS6 system comes with a root privilege escalation vuln in sudoedit
