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.

for e500v2 DPFP support) and will generate appropriate dual-precision

Note: If building a Linux kernel with this toolchain, you will want to make

sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions

from getting into the kernel (which is currently unsupported). At this time,

the kernel build system properly passes those two options, but older kernels

were only passing -mno-spe by default."
