scripts/populate: optimise search loop

Curently, populate will iterate over all ELF (shared objects|executables)
to look for missing NEEDED DSOs, adding to the list at every iterations
of the search loop.

Instead of looking again at previously handled ELF files, recursively
resolve every ELf files.

Also, in case there are a whole lot of files (more than the shell can
accept as arguments list, or creating a command line longer than the
shell can cope with), use a temporary file with the list of files
to search for missing dependencies.

    20       Add support for the Signal Processing Engine.  This will set up

    21       the toolchain so that it supports the SPE ABI extensions. This

    22       mainly targets Freescale e500 processors.

    23       

    24       Setting this option will append "spe" to the end of your target

    25       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc

    26       configure/build system will know to include SPE ABI support.

    27       It will also automatically add "-mabi=spe -mspe" to your

    28       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,

    29       so you do not need to explicitly add them.
