[PATCH 4.14 38/91] powerpc/spufs: add CONFIG_COREDUMP dependency

[Greg Kroah-Hartman]

From: Arnd Bergmann <arnd@xxxxxxxx>

[ Upstream commit b648a5132ca3237a0f1ce5d871fff342b0efcf8a ]

The kernel test robot pointed out a slightly different error message
after recent commit 5456ffdee666 ("powerpc/spufs: simplify spufs core
dumping") to spufs for a configuration that never worked:

   powerpc64-linux-ld: arch/powerpc/platforms/cell/spufs/file.o: in function `.spufs_proxydma_info_dump':
>> file.c:(.text+0x4c68): undefined reference to `.dump_emit'
   powerpc64-linux-ld: arch/powerpc/platforms/cell/spufs/file.o: in function `.spufs_dma_info_dump':
   file.c:(.text+0x4d70): undefined reference to `.dump_emit'
   powerpc64-linux-ld: arch/powerpc/platforms/cell/spufs/file.o: in function `.spufs_wbox_info_dump':
   file.c:(.text+0x4df4): undefined reference to `.dump_emit'

Add a Kconfig dependency to prevent this from happening again.
