The patch cleans up the file lib/decompress_unxz.c by removing all memory
helper functions, e.g., memmove.  By doing so, any architecture's preboot
environment supporting the XZ decompression needs to define its own copy of
any of the missing memory helper functions.

Perhaps a silly question, but why not use
the __builtin variants?

For a lot of cases the __builtin variants just generate a call to the
expected out-of-line function, so you need it anyway.
