Norman Feske c560285d88 build: support library builds via lib/<libname>
This patch adds special handling for lib/<libname> arguments to the
build system, which supersedes the former LIB=<libname> mechanism.
Whereas the old mechanism was limited to a single library, the new
convention allows multiple library arguments, similar to regular
targets. The change brings the two immediate benefits.

First, the streamlining of library and target arguments allows for the
building of libraries via the 'build' command of the run tool.

Second, it alleviates the need for pseudo target.mk files for building
shared libraries that have no direct dependencies, in particular VFS
plugins.

Since this change eases the explicit creation of shared libraries
from run scripts, we may reconsider the automatic implicit building
of shared libraries driven by targets. E.g., while developing a Qt
application, a run script could import the Qt libraries from the
depot and combine those with the developed (fresh built) target without
triggering the build of the Qt libraries in the build directory.

When issueing 'make' without arguments, all targets are built. This
patch applies this behavior to libraries as well, thereby removing the
need for the base/src/lib/target.mk pseudo target as used by the CI
tools to build all libraries.

Note that target.mk files located under src/lib/ are no longer
reachable. Therefore, all run scripts that used to trigger the
build of a shared library via a pseudo target must be adapted.
E.g., 'build lib/vfs/tap' must be replaced by 'build lib/vfs_tap'.

With this patch, the LIB=<libname> option is no longer supported.

Fixes #4599
