    m4/libtool.m4: export AIX TLS symbols
    
    TLS symbols in AIX display a new, different symbol type in nm output.
    Libtool explicitly creates a list of exported symbols for AIX shared
    libraries using nm and does not recognize the new TLS symbols, so
    those symbols are not exported in AIX shared libraries.
    
    This is a regression for TLS support on AIX where TLS symbols or GCC
    "emultls" symbols were listed as global data and exported.
    
    This patch updates libtool.m4 export_symbols_cmds for AIX in two
    locations so that global symbols labeled with "L" for TLS are included
    in the export list.
    
    * m4/libtool.m4 (export_symbols_cmds) [AIX]: Add global TLS "L" symbols.
