Use 64bit relocationswip/D694
Summary:
according to the comments, this was not possible with ancient (pre 2006) versions
of binutils. Even Debian stable has newer versions since a whilte.
Please have a close look if you know something about this; I basically removed
code by looking at the code around it, but do not necessarily know what I am
doing here.
Test Plan: Run validate on Harbormaster
