coreboot-kgpe-d16/src/console/printk.c
Stefan Reinauer 68a564f7ac This patch is what I needed to compile coreboot with LLVM.
- call va_* directly if coreboot is running on GCC so we don't need 
  to maintain hacks to get to stdarg.h
- only define LIBGCC_FILE_NAME if it's an absolute path. GCC and LLVM
  just print "libgcc.a" if the file is not there.
