This won't work. gcc does not respect PATH. Unless you have
-B/usr/bin/ in there, it will not use ld-new.
Here's what it looks like with the *startfile_prefix_spec: stuff.
Because I don't have the static ld-new in this build, I kept the
/tools adjusted ld to show that it won't work. I made a stupic
symlink, too, to show that it will still compile, but with the old ld.
# ln -svf /bin/bash /usr/bin/ld
create symbolic link `/usr/bin/ld' to `/bin/bash'
# cc -print-prog-name=ld
/tools/lib/gcc/i686-pc-linux-gnu/4.0.2/../../../../i686-pc-linux-gnu/bin/ld
gcc doesn't care about PATH.
# cc dummy.c -Wl,--verbose &> dummy.log
# echo $?
0
Still successful despite
# ls -l `type -p ld`
lrwxrwxrwx 1 root root 9 Jan 26 08:23 /usr/bin/ld -> /bin/bash
Now the sanity checks:
# grep SEARCH_DIR dummy.log
SEARCH_DIR("/tools/i686-pc-linux-gnu/lib"); SEARCH_DIR("/tools/lib");
# readelf -l a.out | grep ld-linux
[Requesting program interpreter: /lib/ld-linux.so.2]
# grep succ dummy.log

OK, this isn't a fair test since I don't actually have the adjusted ld
installed anywhere.
The way it is right now, we still need to keep the pass 2 binutils.
If you want to make a symlink in /usr/bin/ld, then you need
-B/usr/bin/.
