This uploads a native mipsel compiler that
is usable (at least as long as you don't work with too recent GNU as/ld,
Turned out I'd still got some old symlinks from when I was tinkering
with David Zhang's stuff. RTL now OK, I'll try a full build in the morning.

Thanks for the warning. I'm on 2.20.1, looks like the version number
window is quite tight.
So most of the problems described in
http://wiki.lazarus.freepascal.org/Native_MIPS_Systems
should not be present anymore...
I'll update that presently. What I want to try doing first is running
the compiler natively (hosted by Qemu), later I might try putting it on
real hardware but I anticipate the endianness issue will take some work.
