[coreboot] compiling coreboot

[ali hagigat]

If i execute only this command at the root folder of Coreboot source tree :
make

Will the project be compiled with GCC of the system or GCC of the system
will be patched and changed or it will be compiled exactly with regular GCC
of the linux operating system?

Besides will be the object files in elf format and when they are linked? Is
there any possibility for other formats?
