x86/build: Drop unnecessary '-ffreestanding' addition to KBUILD_CFLAGS

Now that the minimum supported version of LLVM for building the kernel
has been raised to 17.0.1, the addition of '-ffreestanding' to
KBUILD_CFLAGS for 32-bit x86 is unnecessary, as the linked LLVM bug is
resolved in all supported LLVM versions.

  16cb16e0d285 ("x86/build: Remove -ffreestanding on i386 with GCC")

intended to make the addition of '-ffreestanding' clang only but due to
a bug in the adjusted check from

  d70da12453ac ("hardening: Enable i386 FORTIFY_SOURCE on Clang 16+")

it has been applied for all versions of GCC and clang < 16.0.0. There
are no known problems with removing this for GCC but if one surfaces, it
can be restored under a CONFIG_CC_IS_GCC block.
