[Minios-devel] [UNIKRAFT/GCC PATCH 03/14] Port libbacktrace library

[Charalampos Mainas <Charalampos.Mainas@xxxxxxxxx>]

From: Charalampos Mainas <charalampos.mainas@xxxxxxxxx>

This port also adds the generated config.h and backtrace-supported.h headers.
Another option would have been to generate them during the build.
