[crosstool-ng] patches for glibc-ports-2.6.1

[Julien Dusser <julien dot dusser at irisa dot fr>]

Hello,

I'm testing crosstool-ng to generate gcc for powerpc 405 softfloat.

Current svn 1104 
<http://ymorin.is-a-geek.org/websvn/listing.php?repname=crosstool-NG&path=%2F&rev=1104&sc=1>, 
glibc-port-2.6.1 patches are broken.
Here is a working version of 120-lll_lock_t.patch (problem of path)
I added also a patch for glibc and powerpc nofpu: 
300-powerpc-softfloat.patch
This patch (ref: 
http://sources.redhat.com/ml/libc-ports/2007-06/msg00000.html) is 
working on glibc 2.5 and 2.6.1, but is useless for 2.7.

With this patch it compiles fine.

Regards,

Julien


Propagate the patch from base glibc that changes lll_lock_t into a plain int,
without using a typedef, as glibc-2.7 now does.
