Kumar Gala 0e43b8861b libc: fix armclang compiler warnings with is*() functions 
We get compile warnings of the form:

error: converting the result of
'<<' to a boolean; did you mean
'((__aeabi_ctype_table_ + 1)[(byte)] << 28) != 0'?
 [-Werror,-Wint-in-bool-context]
                if (!isprint(byte)) {
                     ^

Since isprint (and the other is* functions) return an int, change check
to an explicit test against the return value.

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
