Re: gcc 3.0 / glibc 2.2.3 cross-toolchain

["Bradley D. LaRonde" <brad@ltc.com>]

Woohoo!  It works!  Thanks!  I was using H. J. Lu's first patch and that was
broken.  I found the second patch and it worked, except it left the first
line in rtld-ldscript.in, when it really should have removed the file
entirely.  Looks like it's right in the glibc CVS though.

Regards,
Brad
