Fix build when gcc is used and the platform's libc lacks alloca().
include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c
(alloca): Make alloca() globally available by moving the
ultimate ifdef's to ruby/ruby.h. Gcc hides its builtin alloca()
when compiling with -ansi, and linking thus fails on platforms
that lack their own alloca() implementation in libc, which
include OpenBSD and some ports of NetBSD. We use alloca()
everywhere including from within third party C extentions, so
alloca() must be made globally available. [Bug #7307]
addr2line.c (alloca): Replace the alloca() part with the
ultimate ifdef's. [Bug #7307]
