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.

Set the default behavior on alpha to use -mieee since the large majority of
yann@552
     3
time we want this (bad/weird things can happen with packages built without
yann@552
     4
-mieee).

To satisfy those people who may not want -mieee forced on them all the time,
yann@552
     7
we also provide -mno-ieee.
