### Contribution description
A note says "The nomips16 attribute should not really be needed,
it works around a toolchain issue in 2016.05-03."

In fact, in 2018.09-03, the attribute leads to this error:

```cpu/mips32r2_common/thread_arch.c:191:1: error: ‘_mips_handle_exception’ redeclared with conflicting ‘nomips16’ attributes```

This this commit removes the attribute.
Put here the description of your contribution:

- if it's a bug fix, describe the bug that it solves and how it is solved
- you can also give more information to reviewers about how to test your changes

### Testing procedure

Successful build and basic test on any mips32r2 board should suffice.

Details steps to test your contribution:
- which test/example to compile for which board and is there a 'test' command
- how to know that it was not working/available in master
- the expected success test output
