Building for mips

[Daniel Santos]

Hello,

I'm new to the openjdk project, but I would like to build openjdk with
musl on mips (for a 24KEc which is a 32-bit little endian cpu).  Debian
has paved a bit of the way here, so I was hoping to pull in their
patches, but it seems there are a lot of differences between the portola
project and the main line.

My first question is to better understand how the OpenJDK repositories
work -- this is my first experience with mercurial and I'm used to git. 
Is Portola a set of patches that are rebased on to the main line
openjdk, or are patches from the main line imported into Portola upon
each release?

I didn't see a -musl handler in common/autoconf/build-aux/config.sub. 
What machine description do you guys use when building Portola on a
*-linux-musl machine, *-linux-gnu?

Thanks
Daniel
