[Samba4] [FreeBSD] backtrace patch [1/1]

[Timur I. Bakeyev]

Hi!

Here is a small patch that allows to use backtrace() function to generate
stack traces on panic. There is an external, FreeBSD specific library, that
mimics behaviour of the glibc backtrace() and friends functions.

With regards,
Timur.
