So is posix_spawn, as the name implies.

Do you know of any target we support that has fork but not posix_spawn?
Hi Janne,
I differ there.
A longer explanation:
fork() is standard POSIX. Not all systems have posix_spawn. For
those systems which do not have it, we would cause a regression
by simply removing that functionality for this.
The patch is OK from my side if you add fork() as a fallback
