ARMGCC compiled DFU has logging issues.

I am using SDK 14.0.0 with Softdevice S132 V5.0.0 and the accompanied DFU libraries. In the examples\dfu\bootloader_secure_ble example I think the logging system has a problem.

When compiling the debug version of this project using Keil MDK (pca10040_debug\arm5_no_packssecure_dfu_ble_s132_pca10040_debug.uvprojx) the output from RTT looks okay:

When compiling the same version with GCC, the output from RTT looks somewhat wrong:

The sources of the log output are wrong, as I do not believe that the clock is responsible for initializing the flash.

It looks like the loging takes the wrong module name but i dont have that problem using gcc/g++

This is a known issue with SDK v14.0.0 and SDK v14.1.0, which has been fixed in SDK v14.2.0, see the release notes,i.e.

 - Fixed invalid module names in logger output when LTO was used in the GCC compiler.
