 you know how lobsters will sit in a pot that's boiling because the
temperature differential is not big enough? well... it's like that.

 unfortunately, over the past decade+, nobody predicted that the
linker phase would go *anywhere near* 4GB in size.  that would be
INSANE!!  so of *course* they ripped out all of the historic archaic
techniques that dealt efficiently with linking when there's less
memory than can be addressed even by adding Virtual Memory.

 regarding cross-compiling: if you've seen how openembedded uses
bitbake to do cross-compiling (which includes setting an automatic
qemu redirect of autoconf script running and even qemu-emulated gcc
running), you start to get a deep appreciation for the dangers of

 the key one is, you have absolutely no idea if the host correctly
generated the autoconf settings correctly or not.  even running under
qemu is not accepted, because of the risks of qemu giving the wrong
information when compared to native hardware.
