A yes, missed the closing parenthesis of the $(MSYSTEM) variable,
sorry for that.

And just to be extra sure: you also added the line for SRCDIR above
the target, right?

That should be fine, (and not sure whether you really call it with all
the options on the commandline, you can put all of them in
autogen.input so you don't have to specify them every time.

I guess we need to switch to the autogen.sh directly then.

in the block "if ($src_path ne $build_path)" is where the problem
occurs, when $src_path and $build_path aren't really different, but
one is a shortened path and the other is a full-length one. But
looking at your paths, BuildLO4 is only 8 characters long, so there
shouldn't be any need for path shortening/there shouldn't be a
difference between shortened path and long path.

So let's find out what paths the autogen.sh actually uses when
comparing. Remember that autogen.sh is actually perl, so above the "if
($src_path ne $build_path)" line add a line

print STDERR "src_path: -$src_path- build_path: -$build_path-\n";
and you can stick an
exit(1);
in there as well to stop it from messing up the checkout while
debugging that. What kind of difference there'll be between the
src_path and build_path variables should give further hints as to how
to fix that issue.
