The pixhawk is limited to 1MB of flash and is very close to the limit. Older versions of GCC seem to create slightly larger binaries which have pushed you over the limit. You need to either update to a newer version of gcc or comment out modules in the px4fmu-v2 config to save space.

cmake/configs/nuttx_px4fmu-v2_default.cmake
You could add a # in front of drivers/mpu9250 on line 21 and recompile
