Exherbo users and Gentoo scm users: this affects you now. Other Gentoo
users: this will be in the next major release (0.60.0).

The build_options: split and strip values are now gone. They've been
replaced by a single build_options: symbols value with a parameter. You
can set it in use.conf / options.conf like this:

    */* build_options: symbols=split

Legal values are:

    compress:  Split and compress debug symbols
    preserve:  Preserve debug symbols
    split:     Split debug symbols
    strip:     Strip debug symbols

You'll be able to see these in 'cave show', and the docs on the website
will be updated with the release.

It's ok to specify both the old and the new values before or after you
upgrade.

The mappings from old values to new values are:

    -split -strip         preserve
    split strip           split
    -split strip          strip
    split -strip          didn't make sense, so you shouldn't have it

The new 'compress' value is like 'split', except that it also
compresses debug sections, which can save an awful lot of space. This
needs a recent binutils (2.21.51.0.4), and will break older gdb.
