scripts/addToolsVersion: fix handling libelf

libelf has moved to the companion libraries section,
and is no longer in the tools section.

    10 # paths.mk (we can't use  ". paths.mk", as POSIX states that
    11 # $PATH should be searched for, and $PATH most probably doe
    12 # not include "."), hence the "./".

    17 		Usage: ${myname} <--tool> <[options] version [...]> ...
    18 		  'tool' in one of:
    19 		    gcc, binutils, glibc, eglibc, uClibc, newlib, linux, gdb, dmalloc,
    20 		    duma, strace, ltrace, libelf, gmp, mpfr, ppl, cloog, mpc
    21 		
    22 		  Valid options for all tools:
    23 		    --stable, -s, +x   (default)
    24 		      mark the version as being stable (as opposed to experimental, below)
    25 		
    26 		    --experimental, -x, +s
    27 		      mark the version as being experimental (as opposed to stable, above)
    28 		
    29 		    --current, -c, +o   (default)
    30 		      mark the version as being cuurent (as opposed to obsolete, below)
    31 		
    32 		    --obsolete, -o, +c
    33 		      mark the version as being obsolete (as opposed to current, above)
    34 		
    35 		  Note: setting a new tool resets to the defaults: 'stable' and 'current'.
    36 		
    37 		  'version' is a valid version for the specified tool.
    38 		
    39 		  Examples:
    40 		    add stable current version 2.6.19.2 to linux kernel:
    41 		      ${myname} --linux 2.6.19.2
    42 		
    43 		    add experimental obsolete version 2.3.5 and stable current versions 2.6.1
    44 		    and 2.6.2 to glibc, add stable obsolete version 3.3.3 to gcc:
    45 		      ${myname} --glibc -x -o 2.3.5 -s -c 2.6.1 2.6.2 --gcc -o 3.3.3
