There were 3 copies of these flags.  Place them in the
file with gdb_do_syscall, with which they belong.

Separately:

The gdb remote protocol doesn't define an O_BINARY:
https://sourceware.org/gdb/onlinedocs/gdb/Open-Flags.html#Open-Flags
and files are always opened in binary mode:
https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=gdb/remote-fileio.c;h=fe191fb6069a53a3844656a81e77069afa781946;hb=HEAD#l122

so we should probably drop our definition and use of GDB_O_BINARY.

thanks
