Commit ee6d777d3e ("s390/decompressor: support extra debug flags")
added extra debug flags, in particular debug info is created,
depending on config options.
With llvm's IAS this causes this compile warning:
arch/s390/boot/head.S:38:1: warning: DWARF2 only supports one section per compilation unit
.section ".head.text","ax"
^
This is a known problem and was addressed with commit b8a9092330
("Kbuild: do not emit debug info for assembly with LLVM_IAS=1").
Just do the same for s390 to get rid of this warning.
