Yes, because that's the .s target which is meant to be used to convert
only a *single* .c file to assembly in order to stare at the resulting
asm. For example:
make arch/x86/kernel/cpu/common.s
It is a debugging aid - and a very basic and important one - and is not
usually used during a normal kernel build. AFAIK.
So we shouldn't worry about any slowdowns here.
Thx.
