It wouldn't necessarily be slow - does NetBSD support KVM?  The hosts
I use to build the Linux packages that I distribute:

are built using CentOS 6.x and 7.x VMs running qemu/kvm on SmartOS,
and they're able to complete full bulk builds in under 24 hours.

Generally this doesn't work because Linux distributions do not follow
any compatibility guidelines, so glibc and even basic commands are
kept under different directories depending on the distribution.

You can try to minimise this by building everything with
PREFER_PKGSRC, but ultimately you're going to run into problems so I
wouldn't bother.
