Postfix expects a C-library implementation of the DNS stub resolver
routines that is compatible with the original BSD design.
It don't think it is reasonable to curate a list of defective
C-library resolver implementations.
Unless Wietse some day throws in the towel and makes libunbound
or libldns a required dependency for Postfix, we're stuck with
the traditional libresolv interface, and it needs to have a
reasonably complete implementation on your system.
As I already mentioned, even without DANE, musl-libc already
fails to provide adequate controls to disable the search
list (RES_DEFNAMES and RES_DNSRCH).
DO NOT run Postfix over musl-libc.
