Bugzilla Bug 37170

tar in achives containing './' in path (for example)
libpcap-0.8.1/./bpf/net/bpf_filter.c

tar strips anything before './'.
This results in incorrect unpacking:
file bpf/net/bpf_filter.c created but correctly need to be libpcap-0.8.1/bpf/net/bpf_filter.c

Reproducible: Always
Steps to Reproduce:
1. Create dir tmp
2. cd tmp
3. tar xzf /usr/portage/distfiles/libpcap-0.8.1.tar.gz
4. ls
Actual Results:  
you see content of libpcap-0.8.1 (NOT directory itself)


Expected Results:  
you must see libpcap-0.8.1 itself with its content WITHIN IT
