 After tracing the binutils source around gas from the error
 message, it was found that 32-bit toolchains on 32-bit host cannot
 handle 64-bit integer by default configuration (see bfd/bfd-in.h
 and integer_constant() in gas/expr.c).
 
 It requires to specify --enable-64-bit-bfd to bfd/configure or add
 a hint as below to enable 64-bit integer handling.
 
 So I would like to apply this patch, comment?
