[Buildroot] [PATCH 04/52] package/asterisk: enable backtrace when available

[Yann E. MORIN]

asterisk uses backtrace() from execinfo.h to print beuatiful backtraces
when it fails. But execinfo is only reliably available with glibc, while
it is optionbal in uClibc and completely missing in musl.

So, only enable backtrace support for glibc toolchains.
