You don't pass arrays per se to execve(). execve() takes pointers to
arrays. Just construct the array somewhere in your data
segment. Simple example:
section .data
str1: db "foo", 0
str2: db "bar", 0
str3: db "baz", 0
array: dd str1, str2, str3, 0
section .text
push str1 ; filename
push array ; argv
push dword 0 ; envp
call execve
