Subject: [PATCH] lib: crc32: mark function crc32() as __efi_runtime

The function crc32() is needed by the EFI subsystem at runtime. So it has
to be linked into the runtime section together with all dependencies.

Eliminate empty defines local and ZEXPORT.

Mark variables as static which are not exported.
