note: This is awful. Thank you

the current version is makeself has some issue on running linux
particulary on Ubuntu 14.04. I suspect this is the issue on
test passed (but actually failed) only on linux.

Linux (passed with no output messages):

OSX (passed with proper messages):
https://dash.orfeo-toolbox.org/testDetails.php?test=60023362&build=287444

lurking on makeself's bug tracker, it could be a umask issue

I am not sure if this is the exact problem and upgrade will fix
issue for us. Because we are not able to reproduce this bug on same
machine executed under same constraints.
Only change is that one is running via crontab and other directly from
terminal.

GNU ld now enables -Wl,-as-needed by default. This cause issue on
our side in the final package.
ITK: we link with ITK_LIBRARIES which includes, itknetlib and was not
linked with any of OTB module. This bug was seen in windows package
testing.

Shark: This is another example where wl,-as-needed is causing trouble
shark link with a couple of boost libraries but no of them are linked
into libshark.so due to default -Wl,-as-needed. With this option, the
linker will drop an lib or .so on command line if none of it's symbols
are used by the project.

In both cases (ITK and Shark), there are upstream issues. Shark should
not add boost_system to link flags if it is not used in sharklib. Maybe
this boost component is used in examples. I don't know much. It is
really an upstream issue.
Same case with ITK, if itknetlib is built by default, and is not
necessary for the activated itk modules, it should skip that.

To get back old behaviour, we have to use -Wl,no-as-needed.
The other option; Wl-no-undefined is to trigger a link error if an
undefined reference is found.

The exact behaviour of as-needed and no-undefined can be found on GNU LD
man pages (man ld).
