Here's the problem case:

gcc-3.4.x requires glibc headers to be installed
glibc-2.3.x's configure requires kernel headers to be installed.
linux-2.6.x's "make prepare" requires gcc to be installed

It's a circular dependency.  Moving to the sanitized kernel
headers (http://ep09.pld-linux.org/~mmazur/linux-libc-headers/)
may be the only real fix.  The README for that says it
is intended for kernel 2.6.x and glibc 2.3.3 and up, though,
so there might be some problems using it with 2.4 and older
glibc's, who knows.
