The binaries provided inside the klibc package were always compiled with
-shared explicitly. The klibc-extras and klibc-udev were always compiled
without -shared or -static, thus statically linked. This was an
inconsistency, mixing static and shared binaries in the image.

The "bug" I actually fixed was that klcc (without -static or -shared
specified) linked a static binary, while gcc linked a shared binary,
which is inconsistent.

We can discuss building all klibc binaries statically, but then we do it
by specifying -static in LDFLAGS explicitly, not by some weird klcc

About the breakage: When klibc is rebuilt, all klibc tools are rebuilt
at the same time, so nothing should ever break.
