Initially Linux didn't use ELF either, but a.out.
SunOS4 (based on BSD) did use 2-byte alignment on m68k, so I am still
surprised NetBSD didn't follow suit.
SunOS5 (based on SVR4) no longer supported m68k.
I expect (the history of) the gcc sources would tell you more about
the default alignment on other (legacy UNIX) OSes supporting m68k...
