[coreboot] Trouble compiling tint payload

[Andrew Guertin]

I'm having trouble compiling the tint payload.

When following the instructions on the wiki at http://www.coreboot.org/Tint, I 
get an error about lpgcc. I've figured out I need to make the following change 
to the Makefile:

--- Makefile.old        2010-08-23 10:11:33.979039352 -0400
+++ Makefile    2010-08-23 10:11:43.808039821 -0400

-LIBPAYLOAD_DIR := ../libpayload
+LIBPAYLOAD_DIR := ../libpayload/install/libpayload
  CC := $(LIBPAYLOAD_DIR)/bin/lpgcc
  AS := $(LIBPAYLOAD_DIR)/bin/lpas
  # CFLAGS := -Wall -Werror -Os


After that, I try to compile with
make CC=/.../coreboot/util/crossgcc/xgcc/bin/i386-elf-gcc
and get the following errors:

/.../coreboot/util/crossgcc/xgcc/bin/i386-elf-gcc -Wall -Os -c -o tint.o tint.c

If instead of `make CC=/.../coreboot/util/crossgcc/xgcc/bin/i386-elf-gcc` I 
simply call `make`, I get:

...which seems to indicate that the compilation has progressed farther but then 
failed for not having 32bit libgcc (as expected as my system compiler is 64bit).

I'm running Gentoo Linux on an x86_64 machine with no 32-bit libraries, and no 
kernel support for 32-bit binaries. System gcc is 4.4.3, system ld is 
2.20.1.20100303.

Any clues to what I'm doing wrong?
