libc/glibc: repair debugging with gdb (glibc 2.9)

Without this patch, crosstool-ng-built glibc-2.9 prevents
debugging any exeutable with gdb.
gdb says:
[Thread debugging using libthread_db enabled]
find_new_threads_callback: cannot get thread info: generic error

     3 -= BEGIN original header =-

     4 older verisons of glibc would build dl-sysdep as shared-only and dl-support as

     5 static-only.  alpha hooks in a cache variable via dl-auxv.h.  newer versions of

     6 glibc build dl-sysdep as both shared and static which means we now have symbol

     7 duplication for static builds with dl-sysdep and dl-support.  since dl-sysdep

     8 is both shared/static, there is no point in hooking dl-support anymore, so we

     9 can punt it.
