commit b99b1f054d9c704100479ccdfa6879994f195c00

Searching for cpp program path and pass it to SeaBIOS Makefile.

SeaBIOS Makefile requires cpp(C Preprocessor) to build. Modify
    xcompile script to search for cpp program path, and pass it to
    SeaBIOS Makefile.inc. Also pass as(GNU assembler) program path.

This patch makes using crossgcc toolchain to build SeaBIOS payload
    under Mac OSX works. OSX has built-in cpp program, but it works
    differently from GNU CPP, so we need to override it.
