Enable strong stack protector by default for GCC 3 architectures.
Miod says all architectures work with it now (thanks to his fix for
the pf.c bug).

Add strong stack protector mode for the original propolice in GCC3.
This includes additional functions to be protected --- those that
have local array definitions, or have references to local frame
addresses.

Miod verified that this works on real hardware, and not just on the
cross-compiled monster I tested this on.

Add support for position independent executables. This adds compile flags
-fpie & -fPIE which are similar to -fpic & -fPIC except that the resulting
objects can not be used in shared libraries due to an additional
optimization for pie. This also adds the -pie link flag which produces a
pie executable given pic or pie objects. Combining -pie with -static is
currently disabled. The only gcc3 arch that doesn't support pie at moment
is arm due to binutils relocation bugs.

Introduce a new compiler warning, -Wstack-larger-than-N, to report
functions which are too greedy in stack variables.

This is intended to be used for kernel compiles, where this warning will
be enabled for a reasonable size (after a few weeks grace period so that
people can upgrade their compiler).

Please note that this warning relies upon md code, and as such is only
available on platforms OpenBSD runs on; also, the stack size being warned
on is only the local variables size, regardless of the ABI stack usage
requirements and the callee-saved registers; which means a function may
be warning-clean yet need more stack space than meets the eye; the
actual size being checked on may change to include these extras in the
future.

Fix propolice merge error in options list.

initial release of propolice gcc 3.3.2

Add OpenBSD specific features:
- stub for bounded
- kprintf format.
- no strict aliasing in -O2
- no ident for each object file.
- recognize stack-protector option.

Import gcc-3.3.2. Only the compiler. ada frontend removed for space
considerations.
