Fix SH4 register-dump.h for soft-float

[Joseph Myers]

This patch fixes SH4 register-dump.h to declare a variable under the
same conditions on which it is used, to avoid an unused variable error
breaking the build for soft-float.

Tested (compilation only, in conjunction with other fixes) for SH4
soft-float.

	* sysdeps/unix/sysv/linux/sh/sh4/register-dump.h (register_dump):
	Only declare fpregs if [__SH_FPU_ANY__].
