Linking fails with relocation errors about epsilon

[rhaamo]

Adding -fPIC to CFLAGS and CXXFLAGS make it build and link (and it runs).

I didn't tryied to build for the final target, cross-compiled, so I don't know if it would break that.

update: it definitely mess with the real ARM version (doesn't boot and switch to DFU)

[titimoby]

so you mean that adding the flags allow simulator build (I tested it and it works) but this broke the device firmware build ?

[rhaamo]

Yes, adding -fPIC to the build for ARM makes it doesn't boot.

Currently the fix I'm using is:
