gnu-getopt (which is in fact netbsd getopt) includes support for 
optreset, and is compatible with gnu and bsd.

from the readme:

gnu getopt compatibility package for musl

usage:
make; make prefix= DESTDIR= install

then to compile a package, add to
CFLAGS="-Dgetopt=gnu_getopt -Dgetopt_long=gnu_getopt_long 
-Dgetopt_long_only=gnu_getopt_long_only"
LDFLAGS="-lgnu_getopt"
