+ If you answer Y here, the uClibc native shared library loader will
+ support ET_DYN/PIE executables.
+ It requires binutils-2.14.90.0.6 or later and the usage of the

+ More about ET_DYN/PIE binaries on <http://pageexec.virtualave.net/> .
+ WARNING: This option also enables FORCE_SHAREABLE_TEXT_SEGMENTS, so all

+ functions must be written as position independent code (PIC).
