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.
