The "size" tool has been solely used by s390 to enforce .bss section usage
restrictions in early startup code. Since commit 980d5f9ab36b ("s390/boot:
enable .bss section for compressed kernel") and commit 2e83e0eb85ca
("s390: clean .bss before running uncompressed kernel") these restrictions
have been lifted for the decompressor and uncompressed kernel and the
size tool is now unused.

``LLVM_IAS=1`` to enable it.
