scripts/xldd: better find sysroot with old gcc

Only starting with 4.4 does gcc have a -print-sysroot option.
For 4.3 or before, we have to play some tricks:
- ask gcc where libc.so is,
(we expect it in ${sysroot}/usr/lib/libc.so)
- trim /usr/lib/libc.so from the result

     6       Do not use a C library.

     7       

     8       This is usefull if your project is self-contained, does not rely on

     9       an external C library, and provides all the necessary bits.

    10       

    11       Most probably usefull to bootloaders, as they generally don't depend

    12       on the C library.

    13       

    14       If unsure: do *not* choose that, and use another option in the choice.
