When I was debugging my gcc/glibc cross build script (http://kegel.com/crosstool),
I found that glibc-2.2.5 thought it was doing a native compile
if it could run the target executables on the build host.
Maybe 2.2.4 is similar?  Here's a patch to force cross-compilation:

--- glibc-2.2.5/configure.old	2003-05-30 21:51:13.000000000 -0700
+++ glibc-2.2.5/configure	2003-05-30 21:51:23.000000000 -0700

Have you tried my build script?  It does a few other tricks to
get an x86->x86 crosstoolchain to build and test properly, and
you shouldn't need to edit it at all, just create a patch directory
for glibc-2.2.4 and put that patch in it.
