I did most if it by myself. Although I have tried not to break builds  
on other platforms, I have tested it only on OS X.

binutils-2.15.90.0.3, for which there is already a patches directory in  
crosstool, has this patch already applied. I tested the above command  
with BINUTILS_DIR=binutils-2.15.90.0.3. Linux-2.6.6 starts to compile  
fine, until it tries to compile ipt_ecn.c:

[...]
net/ipv4/netfilter/ipt_ecn.c:28: warning: "struct ipt_ECN_info"  
declared inside parameter list
net/ipv4/netfilter/ipt_ecn.c:28: warning: its scope is only this  
definition or declaration, which is probably not what you want
net/ipv4/netfilter/ipt_ecn.c: In function `set_ect_ip':
net/ipv4/netfilter/ipt_ecn.c:31: error: dereferencing pointer to  
incomplete type
net/ipv4/netfilter/ipt_ecn.c:39: error: dereferencing pointer to  
incomplete type
[...]

After disabling network packet filtering, it continues until:

[...]

[...]

However, most gcc-*-glibc-*.dat files ask for binutils-2.14.92.
I backported this patch for binutils-2.14.92 and made it applyable with  
"patch -p1" (attached).
I included it into the correct patches subdirectory.
Unfortunately, when I did the above command line with no BINUTILS_DIR  
assignment, I got:
