c8727fa6e5 Fix Linux getlogin{_r,} implementation
The old implementation uses fd 0 to determine the login TTY.  This
was needed because using /dev/tty it is not possible to deduce the
login TTY.  For some time now there is the pseudo-file
/proc/self/loginuid which directly helps us to find the user.  Prefer
using this file.  It also works if stdin is closed, redirected, or
re-opened.

d8c47894ca Extended ELF ABI version handling only for Linux.
If the OSABI is generic we should not allow the ABI version to be nonzero.
Move all the new functionality into Linux-specific files.

321029f1c3 sparc64: Fix msgrcv()
msgrcv() does not work on sparc64, as it passes the 6th argument using
the ipc kludge, while the kernel waits for a 6 arguments syscall. This
patches fixes the problem by using a sparc64 specific version of
msgrcv.c.
