The s390 kernel is currently not building using the latest versions of the upstream tools.  The following is a reduced test case based upon this failure:

  % cat rod.s
	.section .rodata
	.dc.l 0x1234
	.dc.l 0x5678

   % s390-linux-gnu-as rod.s -o rod.exe
   
   % cat tmp_main.ver

SECTIONS { .rodata : ALIGN(4) { __crc_system_state = .; LONG(0x015af7f4); } }
SECTIONS { .rodata : ALIGN(4) { __crc_static_key_initialized = .; LONG(0xbea5ff1e); } }
SECTIONS { .rodata : ALIGN(4) { __crc_reset_devices = .; LONG(0xc2e587d1); } }
SECTIONS { .rodata : ALIGN(4) { __crc_loops_per_jiffy = .; LONG(0xba497f13); } }

  % s390-linux-gnu-ld -r -o rod.exe rod.o -T tmp_main.ver
  s390-linux-gnu-ld: final link failed: bad value

Whilst the linker script is unusual, the test should pass, and indeed it does so for other architectures.
