[lttng-dev] [PATCH] Fix: multiple definition error with gcc 5.1

[Jérémie Galarneau]

Hi Zifei,

It seems I had missed the patch you had sent with this e-mail. I did end up
having the same issue today as I upgraded to gcc 5.1.

My fix is a combination of what was reported on the open embedded mailing
list (marking the mi and config declarations as extern) and removing what
was left of the function:entry feature.

    Fix: Mark MI and Config string declarations as extern

    This fixes a build issue with GCC 5.1 which would complain about
    these symbols being defined multiple times.

Thanks a lot and sorry for the delay!
