I have no idea why we would change that or how you should do that.
Note that execvp() is a system call. So this would be a kernel
limit, and setrlimit() doesn't let you set this.
I get:
$ getconf ARG_MAX
2097152
And I get that on all the buildds I've tried it too, but that
wasn't under sbuild, if it somehow managed to change that.
man sysconf(3) also has:
BUGS
It is difficult to use ARG_MAX because it is not specified how much of
the argument space for exec(3) is consumed by the user's environment
variables.
