Improve fstack_protector effective target
Effective target fstack_protector fails to return an error for
newlib-based target (such as arm-none-eabi targets) which does not
support stack protector. This is due to the test being too simplist for
stack protection code to be generated by GCC: it does not contain a
local buffer and does not read unknown input.
This commit adds a small local buffer with a copy of the filename to
trigger stack protector code to be generated. The filename is used
instead of the full path so as to ensure the size will fit in the local
buffer.
