+ If you answer Y here, the uClibc native shared library loader will
+ only load shared libraries, which do not need to modify any non-writable
+ segments. These libraries haven't set the DT_TEXTREL tag in the dynamic
+ section (==> objdump). So all your libraries must be compiled with
+ -fPIC or -fpic, and all assembler function must be written as position
+ independend code (PIC).
+ Enabling this option will makes uClibc's shared library loader a
+ little bit smaller and guarantee that no memory will be wasted by badly
+ coded shared libraries.
