[coreboot] r3477 - in trunk/payloads: coreinfo libpayload/bin

[svn at coreboot.org]

Author: stepan
Date: 2008-08-07 17:22:01 +0200 (Thu, 07 Aug 2008)
New Revision: 3477

Modified:
   trunk/payloads/coreinfo/Makefile
   trunk/payloads/libpayload/bin/lpgcc
Log:
fix cross compilationor libpayload / coreinfo by honoring
the setting of CC in the payload (coreinfo) when calling
 
make CC=i386-elf-gcc AS=i386-elf-as AR=i386-elf-ar STRIP=i386-elf-strip

This still does not cope with the hardcoded -fno-stack-protector in
libpayload's Makefile.
