    project: update the -XOPEN_SOURCE requirement.
    
    While _XOPEN_SOURCE=700 is the default for cross-platform components
    of the midipix project, slibtool strives to offer a libtool alternative
    to a range of users as wide as possible, and as such should keep the
    requirements from the host system to a bare minimum.
