RFR: JDK-8307604: gcc12 based Alpine build broken build after JDK-8307301

[Matthias Baesken]

After the harfbuzz 7.2 update we run into

/linuxmuslx86_64/jdk-dev/src/java.desktop/share/native/libharfbuzz/OT/glyf/Glyph.hh:281:8: error: offset '4' outside bounds of constant string [-Werror=array-bounds]
  281 | bool get_points (hb_font_t *font, const accelerator_t &glyf_accelerator,
      | ^~~~~~~~~~
/linuxmuslx86_64/jdk-dev/src/java.desktop/share/native/libharfbuzz/hb-static.cc:45:16: note: '_hb_NullPool' declared here
   45 | uint64_t const _hb_NullPool[(HB_NULL_POOL_SIZE + sizeof (uint64_t) - 1) / sizeof (uint64_t)] = {};

We use gcc12 on Alpine.
Switching off this  'warning as error' fixes the issue.
