There are two solutions for this.  Either use __builtin_alloca directly
(which should still be available even with -fno-builtins.) or write a
alloca() function yourself.  I really don't like the latter.  It is 
"too" low-level, even for a bootloader, and might break things with new 
versions of GCC (even thou I suspect that things like alloca is put in 
some standard somewhere.)
