In projects where I want to do this, I add the following to
configure.in:
dnl Set up a non-clobbering install
ORIG_INSTALL=`realname $INSTALL`
AC_SUBST(ORIG_INSTALL)
case $target in
*linux*)
INSTALL="/usr/bin/install -C"
;;
esac
Obviously a proper feature test would be better, but it works for me :)
Perhaps $target should be something like $build_host if I was going to
cross compile.
