commit 2940021afafb382e51b61d9692bf3ade5edc6223
Author: Daniele Forsi

Print fatal error messages to stderr instead of stdout

This uses die() which was previously unused.
    Before this change an unhelpful error message was printed when make tried
    to parse English text as if it was part of the makefile:
    .xcompile:1: *** missing separator (did you mean TAB instead of 8 spaces?).  Stop.

After this change the first error message at least mentions that iasl is
    missing:
    ERROR: no iasl found
    make: -print-libgcc-file-name: Command not found
    make: -print-libgcc-file-name: Command not found
    make: -print-libgcc-file-name: Command not found
    /bin/sh: 0: Illegal option -
    Makefile.inc:36: *** Please use the coreboot toolchain (or prove that your toolchain works).  Stop.
