debug/gdb: fix runtime sysroot

This patch sets the runtime sysroot to fix the following GDB warning:
"Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code."

The sysroot can later be changed within gdb with the `set sysroot`
command if necessary.

     7 GCC 4.3 changed the location of some of the header files.  I don't
     8 understand why you'd be getting these errors while building GCC since
     9 it provides them.
    10 
    11 With regard to GLIBC, Roland checked in some changes so that the GLIBC
    12 build system could find the new locations of the GCC provided header
    13 files.
