From 699af193594037c98a3d05096283429520775c94 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Fri, 15 Jan 2016 11:47:46 -0700 Subject: arch/x86/Makefile.inc: Update symbol check macro This was breaking the build on OS X, but also wasn't working correctly under linux anymore either. It wouldn't print the illegal symbols when it failed. - Split the generation of the offenders file from the actual check for offending symbols and just send all output to /dev/null. - Rewrite the check for offending symbols in a way that works with OS X. Tested by adding a global variable to romstage and verifying the failure is shown correctly. Verified that it works correctly with no illegal variables.
