linux-user uses the rand function for generating the value of the AT_RANDOM elf
aux vector entry, and explicitly seeds the random number generator with the
current time. This makes it impossible to reproduce runs that use the AT_RANDOM
bytes.
This patch adds a command line option and a matching environment variable for
setting the random seed, so that the AT_RANDOM values can be predictable when
the user chooses. The default is still to seed the random number generator
with the current time.
The difference from version 4 of the patch is only the addition of the line
