--- Comment #7 from Brooks Moses <brooks at gcc dot gnu.org> ---
I have reconfirmed this, in the following things, all for different targets:
* A downloaded Sourcery CodeBench Lite Edition 2010.09 (GCC 4.5.1 with patches)
* A downloaded Sourcery CodeBench Lite Edition 2013.05 (GCC 4.7.3 with patches)
* A local build of our google/gcc-4_8 branch.
* A build of current development trunk.

The problem is very straightforward:

The ${target}/bin/gcc is installed from "gcc-cross", which is created by a
simple "cp" command from "xgcc" -- see the "gcc-cross$(exeext):" rule in
gcc/Makefile.  (The bin/${target}-gcc is installed from "xgcc".)  Thus, the
decorated and undecorated gcc executables are identical.

And, if we run this executable under strace, we will find that it looks for cc1
in things under "../libexec", but not under "../../libexec", which would be the
correct path for the undecorated executable.

--- Comment #8 from Brooks Moses <brooks at gcc dot gnu.org> ---
FWIW, there was some interesting discussion of this on
http://sourceware.org/bugzilla/show_bug.cgi?id=15823.

In particular, Joseph Myers argues that "the bug is installing the files in
$target/bin/ at all ... That directory contains executables from binutils for
internal use by GCC; that's its sole purpose.  The files installed by GCC there
aren't used by GCC (rather, the public installed copy of the driver gets used 
when collect2 needs to call back to the driver), so shouldn't be 
installed."

Given the attention this bug has received in the past three years, and the fact
that this was broken for at least three years before the bug was filed, I'm
inclined to agree.

(There are two or three references online to making the $target/bin/gcc
programs work by setting PATH variables to the relevant libexec subdirectory,
so they're not _completely_ unused.  But nothing ever is.)

I've seen this too, for e.g. crisv32-axis-linux-gnu configured with
/absolute/path/toplevel/configure --target=crisv32-axis-linux-gnu.

Andrew: Isn't this a duplicate report even?  IIRC you were talking on IRC about
entering one, though I guess neither of us did?

------- Comment #3 from ossman at cendio dot se  2010-02-09 09:36 -------
Btw, my workaround for now is to remove the binaries in
/usr/sparc-sun-solaris2.10/bin and replace them with symlinks as gcc will
resolve any symlinks before trying to determine its runtime prefix.
