The installed path to expat and liblldb are wrong.  This results in
the binaries not running on the macOS host. With gdb, we have

$ ./aarch64-oe-linux-gdb
dyld[...]: Library not loaded: libexpat.1.dylib
  Referenced from: <4F097B37-76EC-308F-8022-448023624AD3> /.../aarch64-oe-linux-gdb
  Reason: tried: 'libexpat.1.dylib' (no such file),
  '/System/Volumes/Preboot/Cryptexes/OSlibexpat.1.dylib' (no such
  file), 'libexpat.1.dylib' (no such file), '....'

Running otool shows (some output omitted for clarity):
$ otool -L ./aarch64-oe-linux-gdb
./aarch64-oe-linux-gdb:
	libexpat.1.dylib (compatibility version 12.0.0, current version 12.0.0)
	@loader_path/../../lib/libmpfr.6.dylib (compatibility version 9.0.0, current

One fix would be to patch the configure/build/install scripts to have
the proper path to expat.

The macOS tools give us a simpler option to just run
`install_name_tool` to set it correctly.

lldb-dap has a similar problem with `liblldb`.
