Yes, It works for below combination of options:
  -mthumb -mcpu=cortex-m4
  -mthumb/-marm -march=armv7-a/-mcpu=cortex-a7
But still happens for:
  -mthumb -mcpu=cortex-m3
  -mthumb/-marm
-mcpu=cortex-a7/-mcpu=cortex-a12/-mcpu=cortex-a9/-mcpu=cortex-a15

Maybe it has something to do with the rtx cost.  I will look into it later.
