It's nice to know that gcc-4.0.3 has fixed one part of the problem. However,
not having /usr/lib, /lib, and /usr/local/lib is really bad. The above
output should be compared with the default (GNU) linker search path as,
e.g., in /usr/x86_64-linux-gnu/lib/ldsripts/elf_x86_64.x:

SEARCH_DIR("/usr/x86_64-linux-gnu/lib64");
SEARCH_DIR("/usr/local/lib64");
SEARCH_DIR("/lib64");
SEARCH_DIR("/usr/lib64");
SEARCH_DIR("/usr/x86_64-linux-gnu/lib");
SEARCH_DIR("/usr/local/lib");
SEARCH_DIR("/lib");
SEARCH_DIR("/usr/lib");

containing both .../lib64 and .../lib directories.
