Bugzilla Bug 31474

sys-apps/cpio should depend on virtual/glibc:
ldd `which cpio`
****@portage # ldd `which cpio`
        libnsl.so.1 => /lib/libnsl.so.1 (0x4001f000)
        libc.so.6 => /lib/libc.so.6 (0x40034000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Reproducible: Always
Steps to Reproduce:
1. emerge -evp sys-apps/cpio
2. ldd `which cpio`
3.

Actual Results:  
****@portage # emerge -evp sys-apps/cpio

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] sys-apps/cpio-2.5

Expected Results:  
Something like:

Calculating dependencies ...done!
[ebuild  N    ] sys-libs/glibc-2.3.2-r1  +nls -pic -build -nptl 
[ebuild  N    ] sys-apps/cpio-2.5
