    newlib: Build internal strtold code only if HAVE_LONG_DOUBLE defined
    
    Commit fbace81684f8cbb80a2048c01dc545af247f5cb7
    ("Import correctly working strtold from David M. Gay.")
    introduced two new files, strtorx.c and strtodg.c.  The functions
    are only called from strtold.c.  However, while strtold.c is only
    built if HAVE_LONG_DOUBLE is defined, the patch erroneously added
    the two new files to GENERAL_SOURCES unconditionally.
    
    Fix this by building both files only if HAVE_LONG_DOUBLE has been
    defined.
