#     [for -next only] kconfig: generate include/generated/rustc_cfg
#     
#     This patch is not intended for the mainline.
#     
#     I created this patch for Stephen Rothwell to resolve the merge
#     conflicts in linux-next more easily.
#     
#     The Rust tree is touching scripts/kconfig/confdata.c to generate
#     include/generated/rustc_cfg, which would cause complicated conflicts
#     with the changes from the kbuild tree.
#     
#     I re-implemented it to produce the equaivalent rustc_cfg.
#     
#     I also fixed the memory leak; the original code from the Rust tree
#     did not free the malloc'ed pointer.
#     
#     Stephen:
#     When you resolve the conflicts in confdata.c, please take this one.
