That's pretty fine with me; in the end it's the goal to make the patches
go away as fast as possible... 

My concern is to follow vanilla crosstool as close as possible with what
PTXdist provides. At the moment it is about one day of work to
forward-port the uClibc patches to a new crosstool version and re-run
all the tests. That's something I cannot do that often, and it means
that I'll probably have to stay with 0.32 at the moment (which is bad).

I would be happy if crosstool provided an interface which makes it
easier to switch between glibc and uClibc. At the moment the largest
part of the patch is changing the indentation of the glibc parts,
because they are followed by uClibc parts. That makes the patch
unnecessarily large and lets it look like it was larger than it really
is. 

I'll check if I can restructure the patch in a way that it is easier to
adapt.

No problem; NPTL is surely more important to mainstream than uClibc.
