They _can_ be installed in the same directory (if by same directory you
mean same value for --prefix). gcc for the native host is named "gcc".
gcc for the target by default is named "${target_alias}-gcc".

Methinks you've got things confused a tad.
There's no need to specify --enable-targets for the task at hand.
Certainly you don't need a linker that handles both host and target.

As with gcc, non-native versions of as,ld,objdump,etc. get installed
as ${target_alias}-{ad,ld,objdump,etc.}.  e.g. if you've configured
binutils for powerpc-eabi then you'll get powerpc-eabi-ld, etc.
Note however that these versions of as,ld are not what gcc uses.
${target_alias}-ld is for the user should s/he ever want to call it
directly. A copy of the target linker is installed in (assuming prefix
specified and exec-prefix isn't) $prefix/$target_alias/bin, and this
is what gcc uses.
