[PATCH, MIPS]: Fix internal compiler error: in check_bool_attrs, at recog.c:2218 for micromips attribute

[Robert Suchanek]

Hi,

The original patch had a missing declaration of micromips_globals in mips.h 
that appears to be the cause of segmentation faults when building mips-mti-linux-gnu.
I didn't get any failures just before the submission neither on mips-img-linux-gnu
nor mips64el-linux-gnu and the test case is too trivial to trigger the ICE.

Below is the missing line. With this change mips-mti-linux-gnu builds fine.
The trunk is unstable and needed another patch from PR66181 to build
Glibc. Ok to commit?

I'm in favour of adding such a switch since the testsuite doesn't cover 
a mixture of MIPS and microMIPS code.

Regards,
Robert
