[minicoredumper] [PATCH 0/2] Rework get_stack_pointer for linux above 4.8

[Marco Felsch]

The stack pointer isn't reported to the proc-fs since linux kernel 4.9.
It turned out [0] that we need to parse the kernel coredump ELF-header to
obtain the stack pointers for each thread. This has the disadvantage of
architecture depency. Therefore we keep the proc-fs methode for kernel
below 4.9 and inform the user if he use a kernel > 4.9 and use a
unsupported architecture.

This patch series is an approach to parse the stack pointer from the
ELF-header. Currently only the arm64 is supported because of my target arch.
I've tested it with a linux kernel 4.9 and it works as it should.
