Now see, this is what confuses me.  I built that archive setting
prefix and sysroot to the same directory.  The gcc manual implies that
to make that tarball work anywhere (as you are doing it), sysroot has
to be a subdirectory of prefix.  gcc -v will show you exactly how I
built it... Why does what I did work at all?  I've been trying to
build with sysroot being a subdirectory of prefix, and not having good
luck with it at all.  I thought maybe that might be an issue that
people are having.
