[PATCH 2/2] powerpc/lib: only build ldstfp.o when CONFIG_PPC_FPU is set

From: Christophe Leroy
Date: Mon May 13 2019 - 06:01:50 EST


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")
