sys-libs/glibc: use -mno-sdata, not -fcommon, bug #723268
-fcommon generated PLT references and added double memory
dereference.
-mno-sdata is slightly more efficient as it still sees
globals to be module local varilables and uses GPREL64
(instead of PLT indirection) and uses single memory
dereference.

Package-Manager: Portage-2.3.99, Repoman-2.3.22
