[LyX/master] Fix linking with cmake and included iconv

    Fix linking with cmake and included iconv
    
    Previously, the GNU linker would complain about missing libcharset_relocate.
    The MSVC linker did not complain, since the code that uses 
libcharset_relocate
    does not seem to be sued, so it removed it.
