Re: Building latest Myrddin doesn't work

[Ori Bernstein <ori@xxxxxxxxxxxxxx>]

Ah. I suspect it's related to a few changes stacking together.

First off, 'make clean' was broken. I wasn't actually listing or removing the
system specific files, so they were staying in place. (Fixed in fa136ee).

Second, thanks to trying to work around perf issues in make (49b3d1b79)
means that the copied files no longer depend on the original files, so
they don't get correctly updated. Oops.

This is a legitimate bug, but using patterns is slow, and short of hardcoding
every file copy (maybe I should?), I'm not sure how to fix it. In the common
case (using mbld) this doesn't matter, since mbld just uses the fully
qualified target files, but it matters for bootstrapping.

And finally, I think there may have been an mbld bug, so if you have an old
version of mbld, you may need to delete it and rebuild it.

Anyways, that's a lot of words to say:

	- make clean should be fixed now.
	- install mbld on your path and use it; building
	  should be smoother with it installed.
