commit 06929a556fdc39c8fe12965b69070c8df520a33e

    Fix false-positive CFI failure
    
    When building Chromium with upstream Fontconfig with CFI,
    the following build error is raised:
    
    ../../third_party/fontconfig/src/src/fchash.c:105:21: runtime error:
    control flow integrity check for type 'unsigned int (const void *)'
    failed during indirect function call
    
    This occurs because CFI doesn't like the conversion from
    `unsigned int (const void *)` to `unsigned int (const char *)`.
    To fix this, simply redefine `FcHashFunc` to use `char *` instead.
