Custom Target + BLE - Link step failing

[ladislas]

I'm in the process of moving from the old USCRPL/mbed-cmake to mbed-ce

I've managed to make everything compile but the link step is failing with a lot of undefined reference to __HeapLimit'

it seems related to BLE/Cordio

We are using BLE with mbed-bluenrg-ms

Any idea what I might be doing wrong?

This has been fixed, see #138 #143
