quad.o is only for PPC64, and already included in obj64-y,
so it doesn't have to be in obj-y
Fixes: 31bfdb036f12 ("powerpc: Use instruction emulation infrastructure to handle alignment faults")

The entire code in ldstfp.o is enclosed into #ifdef CONFIG_PPC_FPU,
so there is no point in building it when this config is not selected.
Fixes: cd64d1697cf0 ("powerpc: mtmsrd not defined")
