when glibc runs its tests, it does so by invoking the local library loader.

in Gentoo, we build/run inside of our "sandbox" which itself is linked against

libdl (so that it can load libraries and pull out symbols).  the trouble

is that when you upgrade from an older glibc to the new one, often times

internal symbols change name or abi.  this is normally OK as you cannot use

libc.so from say version 2.3.6 but libpthread.so from say version 2.5, so

we always say "keep all of the glibc libraries from the same build".  but

when glibc runs its tests, it uses dynamic paths to point to its new local

copies of libraries.  if the test doesnt use libdl, then glibc doesnt add

its path, and when sandbox triggers the loading of libdl, glibc does so

from the host system system.  this gets us into the case of all libraries

are from the locally compiled version of glibc except for libdl.so.
