SVN rev 197808 on 2009-10-06 17:14:39Z by rwatson
In rtld's map_object(), use pread(..., 0) rather than read() to read the
ELF header from the front of the file. As all other I/O on the binary
is done using mmap(), this avoids the need for seek privileges on the
file descriptor during run-time linking.
