Thanks! Here are a couple of necessary patches:
- one to be able to build anything *other* than timestamped glibc
- one to create $(SYSROOT)/usr/include/asm if it doesn't already exist

That's enough to get to the "more interesting" problems... :-/

In case anyone else wants to look at this, I attach a cheat sheet of
the commands necessary to set it up - you probably better read that
before you run it...

Cheers

If GLIBG_TIMESTAMP is set but empty (eg clearing the fiels in menuconfig)
the build dies trying to download "glibc-2.7-.tar.bz" and "glibc-2.7-ports-.tar.bz"

Build fails if $(SYSROOT)/use/include/asm does not already exist, so create it.
This patch also avoids creating $(SYSROOT)/usr/include/asm-generic/asm-generic
on subsequent runs.
