crosscompilation of the kernel for MIPS fails with binutils-2_37

[Sudip Mukherjee]

Hi All,

I reported this initially in gcc bugzilla thinking it to be a bug with
the gcc update. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101946)
but it was actually caused by updating to binutils-2_37 from
binutils-2_36_1.

To give more context, the kernel build for mips
"decstation_r4k_defconfig" fails with the error:

arch/mips/dec/prom/locore.S: Assembler messages:
arch/mips/dec/prom/locore.S:29: Error: opcode not supported on this
processor: r4600 (mips3) `rfe'

Both the binutils version has similar configuration:
--target=mips-linux' '--prefix=/src/local' '--enable-64-bit-bfd'
'--disable-nls' '--disable-werror' '--disable-gdb'
'target_alias=mips-linux

Please do let me know if you need any additional information or to
test any patch and I will be happy to help.
