I've digged into this a bit further. In order to make cleaner tests,
I've created a Debian stable chroot with the minimum set of packages
needed to get Buildroot running
(http://free-electrons.com/~thomas/buildroot/pkg-list). And then I tried
to compile two configurations :

 * An ARM configuration, with an internal toolchain (generated by
   Buildroot), with Busybox and libglib2. Compiles perfectly.

   Build log

 * An ARM configuration, with a CodeSourcery toolchain as an external
   toolchain, with Busybox and libglib2. Fails to build libglib2
   because it tries to link against /usr/lib/libdl.so.

   Config

   Build log
   http://free-electrons.com/~thomas/buildroot/build-external.log

So obviously it looks like that the parameter that makes it fail is the
external toolchain. Any idea on what impact it could have on libtool ?

Thanks for your input and ideas,

Thomas
