[coreboot] make crossgcc error

[Richard Simpson]

Hello,

I have recently purchased a Lenovo T60 with the hope of installing
coreboot and I have to say that the process is making me mighty nervous.
I have extracted the default bios and the VGA bios (it has an ATI video
controller). I am running CentOS 7.

I have run 'make menuconfig' and that seems to have worked, but when I
try 'make crossgcc' I get the following error:

Warning: no suitable compiler for arm.
Warning: no suitable compiler for arm64.
Warning: no suitable compiler for mipsel.
Warning: no suitable compiler for riscv.
ERROR: Missing tool: Please install patch (eg using your OS packaging
system)
make[1]: *** [build-i386-without-gdb] Error 1
make: *** [crossgcc-i386] Error 2

I have no idea what to do about this.

Thanks,
