*Hardware* is neither EABI nor OABI, per se.  Your BCM53019 can handle 
armv7 instructions (and nominally instruction sets prior to that, such 
as armv6, armv5, etc).

The choice of OABI or EABI is a software choice.   NetBSD 6 releases 
support the OABI.  NetBSD 7 supports EABI and OABI, but everything from 
armv5 and up went to EABI.  So did specific armv4 ports.

"earmv7hf" is NetBSD shorthand for "ARM EABI, with armv7 instructions 
and hard-float binaries".  It requires NetBSD 7 and later.

We just need to figure out what Apple did on your 5th generation Time 
Capsule.  Based on your results of running "file" on a binary, it looks 
like the OABI is used ("ARM" is reported, instead of "EABI5"), but older 
OABI binaries from NetBSD 6 pkgsrc will not run.
