What version of ld are you running on each? ('apt-cache policy binutils'
or 'ld --version' should tell you.)
According to my reading of the (current?) first answer on
https://stackoverflow.com/questions/46058050/unable-to-compile-unrecognized-relocation
this failure occurs when:
* A version of ld which supports a new relocation type has been released.
* A library has been compiled using that new version.
* You attempt to link against that library using an older version of ld,
which does not yet support that new relocation type.

As a whole, probably not.
You probably do need to upgrade the binutils package, however - and the
dependencies involved in doing that may result in upgrading enough other
low-level things that you might want to upgrade the rest of the system
along with it.
