This seems like it would break linux-user with -cpu cortex-m3, which is used for gcc 
testing, iirc.

(Real m-profile can't run linux, but using the same thumb abi makes testing easier than 
using semihosting and initializing a board model.)

OTOH, we should be able to hard-code the mmuidx for user-only:

    mprofile ? ARMMMUIdx_MUser : ARMMMUIdx_E10_0
