Ooh, no, I would never have said that :-). You may be thinking of
libio/newlib/libstdc++ etc. which aren't used by eCos at all. And for libgcc
you can certainly remove some of the multilib permutations that you know you
won't need, e.g. for recent arm-elf toolchains you can configure with any of
--disable-fpu, --disable-26bit, --disable-underscore, --disable-biendian and
possibly others.

Or you can hack gcc/config/arm/t-arm-elf to set up the multilibs you really
want.

For most users, I would recommend just building all the libgcc multilibs -
they aren't big enough to be a problem.
