LTO: Prevent -flto from creating crashing kernels.

There is something peculiar how default count of lto partitions is created
and used when compiling them. For now just enforce the use of a single one.
GENERIC as it is right now is fine, however turning off certain features
in config, causes the kernel fatal trap 12 very early on boot and reboot.
Note that -g -flto -O2 compilations can easily slurp 1.5-1.8GB of ram!
