[PATCH] Updated glibc-gcc3.patch

[Mark Kettenis]

Two remarks:

* Why does unwind-dw2-fde.c use recursive mutexes?  The origional GCC
  code uses normal mutexes, so I'd expect the libc version to work
  with normal mutexes.  If there is a reason why that's not the case,
  it would at least deserve a comment.

* Given the fact that we want to avoid having any exception handling
  functionality in glibc if possible, it would make sense to make not
  including that code the default, and explicitly enable it for
  existing targets only.
