We have seen in bug 719202 that A has exceeded _SC_ARG_MAX which is
128 KiB.

However, your commit message mentions E2BIG which will trigger at a much
larger value, namely 2 MiB. We are far away from reaching that limit in
any ebuild.

These are separate issues (although related), so I think we should make
it very clear about which one we're talking.
