Hi,
Currently, building gcc for aarch64-darwin host fails due to missing
host_hooks definition.
This patch adds host_hooks definition for aarch64-darwin.
aarch64-darwin is not supported as a target yet, but this allows using
gcc cross-compiler on aarch64-darwin.
I confirmed linking gcc-cross succeed on aarch64 darwin.
gcc/ChangeLog:
* config.host: Add aarch64-darwin host support.
* config/aarch64/host-aarch64-darwin.c: New file.
* config/aarch64/x-darwin: Ditto.
