It is fundamentally impossible to ``fix'' the alloca() implementation
in libc.  alloca() CANNOT be implemented that way.  If GCC's builtin
alloca() is disabled by requesting a strict Standard C environment
(which is not appropriate for FreeBSD anyway), then alloca() is just
an ordinary user symbol and programs expecting the implementation to
supply it should simply fail.
