I've been building CM10.2 for the past month or two and I know how to compile a kernel with a custom toolchain through a BoardConfig flag.

Normally, you can view kernel info, such as the toolchain version used, by opening /proc/version. I was wondering, is there a similar file that I could open to see what toolchain was used to compile the actual ROM?

I followed a guide somewhere to change the toolchain that is used to compile the ROM and I've compiled the ROM itself with a Linaro 4.7 toolchain. Now, I'm not sure if it actually compiled using the Linaro toolchain (I think it may have been built with the regular toolchain used for CM) so I was wondering if there was a way to see (on the device) what toolchain was used for the ROM.

I'd appreciate if someone would help me out here. I don't think it's too much to ask of. Thanks,

CPU Spy shows compiler version when you scroll down to Kernel info.

Unfortunately, that's just the info for the kernel. What I need is the ROM compilation info, which seems impossible to get.
