Reverting sys/compat/linux/common/linux_exec_elf32.c
back to the previous version fixes things for me:

--> $ /emul/linux/usr/bin/uname -bagger
--> /emul/linux/usr/bin/uname: invalid option -- 'b'
--> Try '/emul/linux/usr/bin/uname --help' for more information.

Looks like the implementation of AT_RANDOM messes up the
argument stack (at least for the elf32 case, can't
test the amd64 case myself).
