commit d484d8052775568055547d9e2a3561d3b2176635 Author: Andrew Wu arw@dmp.com.tw Date: Tue Sep 3 20:39:48 2013 +0800
arch/x86/Makefile.inc: Pass $(AS) and $(CPP) to SeaBIOS
SeaBIOS’ Makefile requires cpp (C Preprocessor) to build. Modify the xcompile script to search for cpp program path, and pass it to SeaBIOS’ `Makefile.inc`. Also pass the program path for as (GNU assembler).
This is needed, so the crossgcc toolchain to build the SeaBIOS payload under Mac OSX. OSX ships a cpp program, but it works differently from GNU CPP, so we need to override it.
