Stupid question - shouldn't we use the gcc builtin alloca()?
Some archs seem to have alloca implementations in libc, others don't.

I ask because the recent constifications to execl*.c made them use alloca
on sparc64, and sparc64 has no libc alloca implementation.

So the other part of the question - why is gcc not using the builtin when
complinig libc?
