OpenJDK port for mipsel/musl (OpenWRT)

[Daniel Santos]

I've finally gotten a full built to run and while my project is still in
it's early stages, I thought I would share the repo and point out a few
key patches.  Please note this patch set still has some hacks and needs
a lot of clean up.

Fix bad check for GCC presence and version
<https://git.gsat.us/dansan/openjdk/commit/35405810ecf339971e1c4884a87185788025ce51>
Fix SetupNativeCompilation cross-compiling breakage with --sysroot
<https://git.gsat.us/dansan/openjdk/commit/a3cb7fb9370bd9d7e495b31d3c822e7e3e4ebefa>

And of lessor importance, build can break if you have another libjvm.a
or .so in your library path (like from JamVM):
Fix failed link of libverify.so caused by stray libjvm
<https://git.gsat.us/dansan/openjdk/commit/3297a353b2998de8fb41ec155a87a483fe53cf52>

Here's the repo: https://git.gsat.us/dansan/openjdk

Hopefully I can get this to build from the Icedtea harness next.  I'm
also intent upon running tests via qemu.
