elfutils: fix builds with gcc 4.6

gcc 4.6 (as used in Fedora 15) adds some extra warnings which are
included with Werror. The new unused-but-set variable warning causes
an error in libasm of elfutils. Work around this by removing
unused-but-set from Werror.

(From OE-Core rev: a02eb31697cd977f3587f42bb09b8a9ebcca7a4b)
