scripts/xldd: use user's sed and grep

xldd uses sed and grep as detected by ./configure. This works well if is
used on the machine that build the toolchain.

But if the user moves the toolchain to another machine where sed and grep
are not in the same directory (eg. /bin/sed vs. /usr/bin/sed), then xldd
will stop functionning.

Fix that by using ${SED} and ${GREP} if they are set in the environment.

     1 Patch to correctly handle the MIPS case.

     3 It was build up by Yann E. MORIN <yann.morin.1998@anciens.enib.fr> from some

     4 bits gathered from buildroot, which is LGPL v2.1

    17 I personnaly believe that the resulting code should therefore be
