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.

     4 when building glibc-2.3.3 on cygwin
     5 
     6 Idea from
     7 http://sources.redhat.com/ml/bug-glibc/2002-01/msg00071/glibc-2.2-cygin-shared.patch
     8 Basically, make glibc use .oST as suffix for 'object static'
     9 instead of .oS, since cygwin has trouble distinguishing .os from .oS
    10 (Original patch had .on, but .oST is more mnemonic for 'object static')
    11 
    12 glibc-linuxthreads-2.3.3 also requires a patch, see 
    13 ../glibc-linuxthreads-2.3.3/glibc-linuxthreads-2.3.3-cygwin.patch
