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

     8       Add support for the Signal Processing Engine.  This will set up
     9       the toolchain so that it supports the SPE ABI extensions. This
    10       mainly targets Freescale e500 processors.
    11       
    12       Setting this option will append "spe" to the end of your target
    13       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    14       configure/build system will know to include SPE ABI support.
    15       It will also automatically add "-mabi=spe -mspe" to your
    16       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
    17       so you do not need to explicitly add them.
