scripts/functions: fix endless loop in debug-shell with IO redirection

CT_DEBUG_INTERACTIVE is disabled when stdin, stdout or
stderr are redirected, but the check is only done at
the start of the build and doesn't catch when individual
build commands use redirection. When stdin is redirected
it will cause the debug shell to exit immediately, causing
and endless loop. Thus, save the stdin/our/err file handles
and restore them before invoking the debug shell.

      In case you have trouble with dynamic loading of shared libraries,
yann@175
    23
      you will find that a static gdbserver comes in handy.

      gdbserver >= 7.2 comes with an optional library to use tracepoints,
yann@2986
    31
      the In Process Agent (IPA) library, libinproctrace.so.
yann@2986
    32
      
yann@2986
    33
      Say 'y' if you indend to use tracepoints when debugging your
yann@2986
    34
      programs with gdbserver.
yann@2986
    35
      
yann@2986
    36
      Note: Currently, building this library is not possible when the
yann@2986
    37
            gdbserver is built statically. This is a limitation in
yann@2986
    38
            crosstool-NG, so do not bug upstream about it...
