My mistake, The build is failing on the attached config and not for 
'pseries_le_defconfig'

Sounds like the assembler could not build the 32 bit assembly files. Has
the build succeeded with the same compiler/toolchain and options before?

You're building 32-bit no-smp...

CONFIG_SMP=y
CONFIG_WORD_SIZE=64

... but your config says otherwise.  Some (re-)configuration mishap?
