[klibc] Build and install shared binaries only if KLIBCSHAREDFLAGS is defined
The shared library build has never worked on ia64, and Debian has a
longstanding patch that changes the install targets to install static
binaries for ia64. This can be generalised to checking whether
KLIBCSHAREDFLAGS is defined, as without that we can't expect to build
a working shared library.
* Include the necessary files in scripts/Kbuild.install so that
KLIBCSHAREDFLAGS is defined at install time.
* Install static binaries instead of shared if KLIBCSHAREDFLAGS is
not defined.
* Only install the shared library if KLIBCSHAREDFLAGS is defined.
* Only build the shared library and binaries if KLIBCSHAREDFLAGS is
defined.
