Impact: no default -fno-stack-protector if stackp is enabled, cleanup

Stackprotector make rules had the following problems.

* cc support test and warning are scattered across makefile and
  kernel/panic.c.

* -fno-stack-protector was always added regardless of configuration.

Update such that cc support test and warning are contained in makefile
and -fno-stack-protector is added iff stackp is turned off.  While at
it, prepare for 32bit support.

[PATCH] Add the -fstack-protector option to the CFLAGS 2006-09-26T08:52:39+00:00 Arjan van de Ven arjan@linux.intel.com 2006-09-26T08:52:39+00:00 4f7fd4d7a79193ceda4ce77f75e22917d33fa154 Add a feature check that checks that the gcc compiler has stack-protector support and has the bugfix for PR28281 to make this work in kernel mode. The easiest solution I could find was to have a shell script in scripts/ to do the detection; if needed we can make this fancier in the future without making the makefile too complex.
