[PATCH v3 02/14] x86/stackprotector/64: Remove stack protector test script

[Brian Gerst <brgerst@gmail.com>]

This test for the stack protector was added in 2006 to make sure the
compiler had the PR28281 patch applied.  With GCC 5.1 being the minimum
supported compiler now, it is no longer necessary.
