I've added this tidbit to the README:

Upgrading cross compilers

It is possible to upgrade the musl version in a musl-cross cross compiler
without rebuilding the entire cross compiler prefix from scratch. Simply
download and extract the new version of musl, then configure it like so:

     ./configure --prefix="<prefix>/<triple>" CC="<triple>-gcc"

Where "<prefix>" is the prefix the cross compiler root was 
to, and <triple> is the GNU-style target triple (e.g. i486-linux-microcosm).

No other changes are needed, upgrading is really quite trivial.

With valediction,
