Add skeleton for newlib:
- config file, with only version selection
- build script, with empty functions
- added --newlib to scripts/addToolVersion.sh

    12 Usage: ${myname} <tool> <[options] version [...]> ...
    13   'tool' in one of:
    14     --gcc, --binutils, --glibc, --eglibc, --uClibc, --newlib,
    15     --linux, --gdb, --dmalloc, --duma, --strace, --ltrace,
    16     --libelf, --gmp, --mpfr
    17 
    18   Valid options for all tools:
    19     --stable, -s, +x   (default)
    20       mark the version as being stable (as opposed to experimental, below)
    21 
    22     --experimental, -x, +s
    23       mark the version as being experimental (as opposed to stable, above)
    24 
    25     --current, -c, +o   (default)
    26       mark the version as being cuurent (as opposed to obsolete, below)
    27 
    28     --obsolete, -o, +c
    29       mark the version as being obsolete (as opposed to current, above)
    30 
    31   Note: setting a new tool resets to the defaults: 'stable' and 'current'.
    32 
    33   'version' is a valid version for the specified tool.
    34 
    35   Examples:
    36     add stable current version 2.6.19.2 to linux kernel:
    37       ${myname} --linux 2.6.19.2
    38 
    39     add experimental obsolete version 2.3.5 and stable current versions 2.6.1
    40     and 2.6.2 to glibc, add stable obsolete version 3.3.3 to gcc:
    41       ${myname} --glibc -x -o 2.3.5 -s -c 2.6.1 2.6.2 --gcc -o 3.3.3
