[systemd-devel] [RFC 00/25] Compile against the musl libc

Hi,
Around the internet one can read statements such as "systemd
is designed with glibc in mind" and "the systemd developers' idea
of a standard libc is one that has bug-for-bug compatibility with
glibc". So in a fit of naivety I decided to test this out and see
how much work it would take to make systemd work with musl.
The real reason is of course that I'd like to see systemd running
on my router and other small devices that usually run some OpenWRT
derivative.
This series makes systemd compile cleanly against musl 1.1.4 with
a minimal configuration and also fixes a few runtime errors. It is
only lightly tested and a few of patches could definitely be done
in a nicer, more generic way. Also I'd love to get even more stuff
working like eg. networkd and resolved. However I would like some
early feedback and see if this is something that could one day make
it upstream or I'm just wasting my time.
The first two patches are not strictly needed, but it makes the
compilation much quieter and they are correct according POSIX.
