First off thank you all for your time and information, and putting up 
with me learning and trying to get things working!!
Yes you are correct. Nothing in the images or packages fail, but the 
build machine itself segfaults. Then if I put the image on my BB-XM 
sdcard they boot and "run" but things are not right, such as directories 
that should not be there are, some do not build a fully functioning 
package, such as task-native-sdk.

No I am not sure about it. As I am just trying to watch it build and 
look for the build machine to segfault and see what packages it is 
working on. Though after further messing with expat I think you are 
correct in doubting that is the one causing it.

I just did a clean build of perl with no rm_work enabled, and I am 
trying to dig through the logs and info. From your earlier 
advice/mentioning of libtool-cross I do notice some things while it is 
building according to the info. I will post some of what stood out to 
me, which may in turn mean nothing. If I can post anymore of the logs or 
anything please let me know. I did notice today setting things to build 
one at a time, that it does appear that its working on libtool-cross, 
but again I could be wrong.

I will do as suggested as well as do a full image build again and see if 
I can find out all that is not working. Thank you for the extra 
debugging info and suggestions. Are there any keywords to search through 
all the files for including the normal log files, it may help me track 
down things even further.

I really am not trying to be a pain in the a** and would like to get 
things sorted out and understood on my side. Honestly if the resulting 
images worked and did not get any extra folders in their paths I would 
not care about the resulting segfaults on the build machine.

Another side note, I am borrowing another build machine for a few days 
to see, this is a non nvidia machine just in case that is the bad 
variable in both machines.
