This option was enabled, and now, after I have disabled this option and rebuild
everything, it seems to work fine.

- Is there an incomaptibility bewteen stack prot4ectiona nd ucLibC or my alix
target system?

- Could it be, that some choosen value in my kernels .config might be the cause
of my trouble?

- Will Buildroot 2010.11 allow me to use stack protection on my target system?

- How does the %gs register fit into this problem? I have learned, that this
register is related to thread local storage, but it is hard to find information
about x86 register usage on linux systems on the web.

73, Mario
