kill unused dump_fpu() instances
dump_fpu() is used only on the architectures that support elf and have neither CORE_DUMP_USE_REGSET nor ELF_CORE_COPY_FPREGS defined. Currently that's csky, m68k, microblaze, nds32 and unicore32. The rest of the instances are dead code. NB: THIS MUST GO AFTER ELF_FDPIC CONVERSION Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
