Now these are enabled by default, I see the following error ...

Yes this is with an older toolchain that uses an older assembler (GNU assembler
(crosstool-NG linaro-1.13.1-4.7-2013.04-20130415 - Linaro GCC 2013.04) 2.23.1),
however, I am curious if older toolchains not supporting the 'crc' arch_extension
are deprecated now?

Cheers
Jon
