First of all, sorry for taking so long. I have just found the root of
this problem, in the strip binary from the binutils package.

In lenny (binutils 2.18.1~cvs20080103-7), 'strip --strip-debug libdl.a'
works, but 'strip --strip-debug some_directories/libdl.a' produces a
'Malformed archived'.

In sid (binutils 2.19.1-1) both calls to strip actually works, with the
same libdl.a binary (coming from libc6-dev-mips64 2.7-18).

So this is definitely a binutils bug.
