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. (From OE-Core rev: 72336003741fb16a7ecdd6b753eae56310413ff7) Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
