[Bug bootstrap/25794] New: gcc won't link to new local glibc

["davek at csh dot rit dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

I can't figure out how to get gcc to build using a local build of glibc.  I've
built and installed glibc-2.3.6 in /usr/glibc2.  As I understand it, I need to
make a cross-compiler in order to make gcc with the new glibc2 (nothing told me
to do this, its just the only way I can kinda get it to work)  Here's my
gcc-build configuration:

../gcc-4.0.2/configure --enable-languages=c,c++ --with-sysroot=/usr/glibc2
--with-newlib

and my build command:

make  BOOT_CFLAGS="-Wl,--dynamic-linker=/usr/glibc2/lib/ld-linux.so.2"
bootstrap4

which will make the stage1 compiler, but will fail as soon as it tries to use
it ->

It's still linking against /lib/ld-linux.so.2, which I don't think it should
be.  I'm sure its a magic variable I'm not setting somewhere.

In short: how do you compile gcc with a local build of glibc?
