It appears that only -c and -m are used in GCC's installation.
For BSD install, the default is to delete the original file and -c
suppresses it. For GNU install, -c is a no-op and the default is
not to delete the original, therefore every install command must include
the -c switch.
We never use the -o flag, so I don't think that differences with respect
to ownership will matter (I can't imagine AIX install would change
ownership on its own). Perhaps there's a difference if -m is not
specified? (I can see two reasonable behaviors: preserve permission or
use the umask of the person running the command).

OK, but on systems like Solaris and AIX, I think we need to look
for /usr/ucb/install even if /usr/ucb is not on the path.
