Stephanos Ioannidis 4735e10630 libc: minimal: Introduce CONFIG_MINIMAL_LIBC_NON_REENTRANT_FUNCTIONS This commit introduces a new configuration called `CONFIG_MINIMAL_LIBC_NON_REENTRANT_FUNCTIONS`, which enables the traditional non-reentrant (i.e. not thread-safe) version of the C standard library functions such as rand() and gmtime() when the respective configs are enabled. The non-reentrant functions make use of the globals and require an additional memory partition (MPU region), which is scarce on low-end devices, when CONFIG_USERSPACE=y. The purpose of this option is to classify the MPU resource intensive functions as a separate category and only enable them when there is a demand for such.

Title: Kernel Access to Standard Libraries

Description:

This test verifies kernel access to the standard C libraries.
It is intended to catch issues in which a library is completely absent
or non-functional, and is NOT intended to be a comprehensive test suite
of all functionality provided by the libraries.

--------------------------------------------------------------------------------

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
