It calls gcc -print-file-name and on my system the path returned is actually a symlinked directory within the staging_dir, for some reason. It uses the result to call find, but find won't follow the symlink and then doesn't find the libraries.
My external toolchain was built by a different buildroot project and lives in the same staging dir. gcc -print-file-name is returning
/home/hamish/work/elara/buildroot/build_armeb/staging_dir/lib/gcc/armeb-linux-uclibcgnu/4.1.2/../../../../armeb-linux-uclibcgnu/lib
which is a symlink to
/home/hamish/work/elara/buildroot/build_armeb/staging_dir/lib/gcc/armeb-linux-uclibcgnu/4.1.2/../../../../lib
Adding -H to find causes it to follow links in the command-line parameters (but not during the actual find), which solves it.
Another alternative would be some sort of path canonicalisation tool, like $(realpath ...) in Make, but there doesn't appear to be a standard POSIX shell function for this.
The attached patch adds -H to the find flags.
