Fix uclibc thumb support - with these patches and by disabling the ARM
specific string asm in uclibc it is possible to run at least some thumb
executables on ucslugc. The changes can be incorporated into other
distros by setting thumb-interwork in OVERRIDES - the changes do change
the way ARM code executes (necessarily). (Changes have also been submitted
as bug 385 to uclibc.org).
