title: How to build statically against musl-libc on gentoo (glibc profile) and clang?
body: <p>I'm not sure if this belongs on superuser instead of stackoverflow, at least for the first part, but for starters, how do I install <code>sys-libs/musl</code> (or any other alt <code>libc</code> for that matter) without replacing glibc or switching to the musl profile; secondly, how do I tell <code>clang</code> to statically link against this library (or, again, any other alt <code>libc</code>) as opposed to the system <code>libc</code> (<code>sys-libs/glibc</code>)?</p>
