    docs: Fix 'modff' reference in extend.texi
    
    In commit a2a919aa501e3 (2003), built-ins for modf and modff were added.
    In extend.texi, section "Other Builtins", "modf" was added to the paragraph
    "There are also built-in versions of the ISO C99 functions [...]" and
    "modf" was also added to the paragraph "The ISO C90 functions [...]".
    "modff" was not added to either paragraph.
    
    Based on the context clues about where "modfl" and other similar function
    pairs like "powf/powl" appear, I believe the reference to "modf" in the
    first paragraph (C99) should instead be "modff".
