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

    38       Say 'y' here, unless you don't want shared libraries.
    39       
    40       You might not want shared libraries if you're building for a target that
    41       don't support it (maybe some nommu targets, for example, or bare metal).
