uclibc: Get uclibc working in thumb mode.
* WARNING!! Do not use bintils 2.19 or 2.19.1
when compiling in thumb mode. The veneer generation
does not work as expected. Use binutils 2.18 or binutils_cvs
* Move LEAD_SONAME into uclibc.inc
* Use no optimizations while compiling ldso.c
to over come a gcc ICE
* Use ARM mode resolver for thumb mode. The
resolver depends on ip register and if we
use thumb function for _dl_linux_resolve then
it adds a veneer which corrupts ip.
