The given $prefix should be some 'absolute' pathname, the default is
'/usr/local' when no '--prefix=$prefix' is given. Yours is 'relative'
to some directory.

Hard to say what is the search root for these, probably the main $BUILD
directory. In any case there seems to be nothing which the configure
script expects, here an 'objdump' for the 'arm-elf' target...

Of course you should first have binutils for 'arm-elf' in the
'$prefix/bin' (for humans and this dir in PATH) and in
'$prefix/arm-elf/bin' (for the GCC to be built). The
'path-to/arm-elf-gcc-4.5.0/arm-elf/bin/objdump' shows this
scheme with your given $prefix and $target values.
