The 4 last options are trying to point to the target binutils,
including 'as' and 'ld' in 'bin', and to the target C library,
in 'lib' and '*include'...

In '/usr/local/gcc-4.2.3-x-i386/i386-apple-darwin/bin' you should
have the bare name 'as' and 'ld' plus some other binutils for the
Darwin/i386 target. And in '/usr/local/gcc-4.2.3-x-i386/bin' you
should have those 'i386-apple-darwin-as' and 'i386-apple-darwin-ld'
and other binutils for the human users, including configure scripts.

The obvious reason is that you haven't the target binutils... Where
are they?  Just as well you should have the Darwin/i386 C libraries
preinstalled before starting to configure and build GCC !

In a native GCC build these target things are already there, in
'/usr/bin', '/usr/lib' and '/usr/include', but in a cross GCC
build the $tooldir should have those 'bin', 'lib' and '*include'
directories filled with the target stuff before the build... Or
they should be in the '$sysroot/usr' if one prefers the
'--with-sysroot=$sysroot'. But in Darwin case the Apple's 'ld'
probably cannot understand this search scheme...
