Of course v850 has different machine language from x86, the ELF object
format is different from the COFF-based PE format in Cygwin/x86 etc. So
different directives in assembly made for ELF format will not be
understood by a PE-format assembler...

The GNU assembler will be configured for only one CPU (family), in this
case it should be configured and built for the same 'v850-elf' target as
the GCC...

What else you have forgotten to produce?  Have you any C-library ?  The
'--with-newlib' says that you are going to use the 'newlib' as this and
when one cannot produce even a "Hello World" application for the target
without a C library, then maybe you would like to have that... Maybe
also a debugger/simulator like GDB for 'v850-elf' could be useful...
