In previous versions I used the linux32/dmd with the -m64

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
