From 744c9a897b74ad66d065791593e25a05e4b6f6a1 Mon Sep 17 00:00:00 2001

Subject: [PATCH] src: Make arch-syscall-check work in VPATH build
The aim of arch-syscall-check test is to check for syscalls
missing implementation. It does so by comparing two files:
1) src/syscalls.csv
2) include/seccomp-syscalls.h
However, due to use of relative paths these files are not found
when doing a VPATH build. But, we can re-use an idea from GNU
coreutils and get an absolute path to the source dir. All that's
needed then is to prefix those two paths with the source dir
path.
