I occasionally take time out to mess with uClibc and try to compile GentooWithuClibc. I'm trying as close to a default install as I can, so I'm not entirely disabling NLS support. I am using the -nls USE flag, but some packages like glib require NLS. So, I created FakeIconvAndGettext static libraries that I install and remove as needed by individual packages.
There's a problem compiling a uClibcLinuxKernel because it expects NLS to be available.
