Gentoo embedded
From ElphelWiki
In order to get Embedded support somethings obviously need to be compiled. Now this is not yet going smoothly but I'll give some indication what can be done to fix it and where I am strugling.
I am able to compile uclibc-0.29 with gcc-4.3.1, but out of the box glibc or uclibc is not possible. I'll try to get the ebuild of uclibc-0.29 and see if I can make some changes to it so it will leave us a successful uclibc. (That will still lack pthreads...)
