[Buildroot] [PATCH 1/1] package/ruby: disable use of stack protector when not available

[Brendan Heading <brendanheading@gmail.com>]

Fixes:
http://autobuild.buildroot.net/results/22e/22eced2dc9ca1bc90ef193b4dc40891c47157e89/

ruby, by default, attempts to use the stack protector if configure detects
that it exists. The stack protector detection does not attempt to link
libssp, which can cause a false positive.

Instead, check if the stack protector is enabled in the buildroot
toolchain config, and set the stack_protector=no environment variable to
force the stack protector off.
