[dm-devel] [PATCH 1/2] multipath-tools: Replace -fstack-protector with -fstack-protector-strong

[Xose Vazquez Perez]

-fstack-protector-strong
    Like -fstack-protector but includes additional functions to be protected
    --- those that have local array definitions, or have references to local
    frame addresses.

gcc-4.9.0(April 22, 2014) required.

This flag is used by default in Fedora:
