From 72336003741fb16a7ecdd6b753eae56310413ff7 Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Tue, 11 Oct 2016 13:19:43 +0100 Subject: lib/oe/qa: add ELF machine to string function Add a function (and test suite) to turn the ELF machine field (e_machine) into a string, so we can tell the user "x86-64" instead of 0x3E.
