For consistency with other flags we pass in Rust, please avoid the
space after `-C`.

By the way, perhaps we could already add others like (untested):

 ifeq ($(CONFIG_ARM64_USE_LSE_ATOMICS),y)
+KBUILD_RUSTFLAGS += -Ctarget-feature="+lse"
   ifneq ($(CONFIG_ARM64_LSE_ATOMICS),y)
        @echo "warning: LSE atomics not supported by binutils" >&2
   endif

This one in particular (LSE) came up in a Binder discussion yesterday.

Cheers,
Miguel
