This patch introduces the -seed command line option and the
QEMU_RAND_SEED environment variable for setting the random seed, which
is used for the AT_RANDOM ELF aux entry.

  linux-user: Fix fault address truncation AArch64

On AArch64 the si_addr field of siginfo_t is truncated to 32 bits
because the fault address passes through an uint32_t variable.

Follow Peters suggestion and drop the uint32_t variable
since its only used once in the Aarch64 loop.

  elf: take phdr offset into account when calculating the program load address

The first program header does not necessarily start at offset 0. This change
corresponds to what the Linux kernel does in load_elf_binary().
