[PATCH] x86/Kconfig: Fix dependency for X86_DEBUG_FPU

[Shuah Khan <skhan@linuxfoundation.org>]

Compile fails when X86_DEBUG_FPU is enabled and X86_REQUIRED_FEATURE_FPU is
disabled. Add explicit dependency on X86_REQUIRED_FEATURE_FPU to fix it.

../arch/x86/kernel/fpu/regset.c:411:(.text+0x4cf2f): undefined reference to `fpregs_soft_get'
ld: vmlinux.o: in function `fpregs_set':
../arch/x86/kernel/fpu/regset.c:445:(.text+0x4d0da): undefined reference to `fpregs_soft_set'
ld: vmlinux.o: in function `copy_fpstate_to_sigframe':
../arch/x86/kernel/fpu/signal.c:197:(.text+0x4da98): undefined reference to `fpregs_soft_get'

6.14 compile worked without X86_REQUIRED_FEATURE_FPU enabled. Might be a
new dependency. Enabling X86_REQUIRED_FEATURE_FPU fixed it for me on my
test system.
