nrf51822 target link error: duplicate symbols SystemCoreClockUpdate, SystemCoreClock

Hi,

I've imported the blinking project (https://developer.mbed.org/teams/Icarus-Sensors/code/Blinking-Led/) to compile locally

Online the build is ok and got it working on the board

But when I try to compile on my computer the link doesn't work correctly due to duplicate symbols: - SystemCoreClockUpdate - SystemCoreClock

I tried also with armgcc toolchain 5_2-2015q4 and got the same result

Any idea ?

Thanks Franck
