I don't really think it is general library search paths which are
the problem. It is the case where the static linker needs to pull
in a library because of a DT_NEEDED tag in some other library it
pulled in. In this situation, I think the static linker tries to
act like the dynamic linker would wrt searching for the libraries.
So adding explicit -L/usr/lib64 doesn't help. /etc/ld.so.cache is
consulted for this special search so I used that as a workaround.
But /usr/lib64 should not need to be in /etc/ld.so.cache, so there
is probably some minor thing missing from the binutils sources or
in the configure command used to build it.
