Keith Packard 623a6d972b tests/mem_alloc: Eliminate alloc warnings. Define _BSD_SOURCE We need to keep gcc from complaining about large calloc/malloc/realloc sizes as that's what we're testing. Define _BSD_SOURCE so that libraries sharing the glibc convention (like newlib and picolibc) for controlling the API level visible to applications will declare reallocarray(3), which is an OpenBSD extension to the C library.

Title: Kernel Access to Dynamic Memory Allocation functions provided by
Standard Libraries

Description:

This test verifies kernel access to the dynamic memory allocation functions
provided by standard C libraries supported in Zephyr:
NEWLIB and MINIMAL_LIB.
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Problems caused by outdated project information can be addressed by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
