Sample Questions and s390/s390x status

[Harold Grovesteen <h dot grovsteen at tx dot rr dot com>]

I have noticed that there are a number of paths in the configuration.  
Some I have tailored for my purposes.  What is the expectation with 
regards to these settings in the sample configs?  I would prefer to get 
this right rather than having to redo the patches to satisfy an 
undocumented expectation.

Suggestion for Yann, a section in the overview.txt on what should or 
should not be set in the samples with regard to the environment would be 
good.  How should the tarball directory or prefix, etc., be set for a 
sample to be acceptable.

I spent a fair amount of time yesterday backing out the suggested config 
settings.  Each toolchain build takes about 35 minutes on my machine, so 
this is time consuming.  The good news is that they run perfectly fine. 
TLS was detected.  Threads were properly built.  Default optimization 
worked.  Binutils cross tool supports 32 and 64 bit ELFS.  All of the 
source is still unpatched, not having applied the supplied patches.  I 
have yet to change the variable settings in s390[x].sh as suggested.  
That is for this morning.

On the next set of patches:
Yann, it would really be easier for me to submit both architectures and 
samples as one patch.  Are you willing to accept these changes that 
way?  That would eliminate the need to go through the patch build 
exercise multiple times and eliminate the "clean" issue with s390.  Just 
asking.

On the glibc configuration issue I first encountered:
So far this has not reappeared.  I supplied a fresh install directory 
and it did not happen.  Based upon Mike's input, I suspect it only 
happens on a fresh install when there is nothing left over from a 
previous build.  There is also no answer to why by glibc patch appeared 
to get past the issue.  I am going to try building with an empty target 
directory to see if this reproduces the problem.  I really want to be 
confident this issue does not hit someone who attempts to build one of 
these toolchains with crosstool-ng the first time.

Thanks,
Harold Grovesteen
