Emery Hemingway 6819c43a05 Add stack protector storage to base library
This patch adds the items necessary for building Genode components with
stack protection enabled, but it is not initialized at runtime. They are
provided at the moment as a convenience and do not implement a security
feature.

This directory contains library description files.  Each '<libname>.mk' file
holds the instruction for building the library '<libname>'. These makefiles are
never used directly but they are called from the build system when required.
When called, the build system passes the following variables:

:'BASE_DIR': This is the base directory of the source tree.

Source codes are specified by setting the 'SRC_CC' and 'SRC_C' variables.
The source code locations must be specified via 'vpath'.
A library can include other libraries by setting the 'LIBS'
variable.

Each '<libname>.mk' file must include the 'lib.mk' role file:

! include $(BASE_DIR)/mk/lib.mk

Libraries implementing one and the same library interface may have specific
implementations for different platforms. Such platform-specific '<libname>.mk'
files should be placed into corresponding subdirectories. For example, the
'linux'-specific implementation of the 'server' library resides in the 'linux/'
subdirectory. The build system automatically searches the right '<libname>.mk'
file by evaluating the 'SPECS' configuration variable. If 'SPECS' is set to
'host linux', the build system will look into the directories './', './host',
and './linux'.
