Because what matters is the standards; POSIX in this case.

glibc and BSD are not the only platforms. Other platforms that have vasprintf
are macOS, Solaris, Cygwin, Android. It would be hard to argue that
Gnulib should override vasprintf on some of these platforms, for a
change that glibc has adopted for the sake of crappy programs.

As usual, we can have a *-gnu variant of the modules. The question is
whether such a change in behaviour is worth all the implementation effort.
