Log Message:
binutils, gdb: fix build und Xcode 16.3

Apply https://github.com/madler/zlib/commit/4bd9a71f3539b5ce47f0c67ab5e01f3196dc8ef9
This removes the #defines for fdopen which isn't used by the zlib code anymore.
It also removes a bogus use of "|| defined(TARGET_OS_MAC)" (now defined by
default by the Xcode compiler) which caused a redefinition of OS_CODE.

First reported by Greg Woods:

Probably worth pulling up to -10 and -9 but very likely needs to be done via
a patch.

Only tested by a full amd64 build.  So the {binutils,gdb}.old change is
untested, but the diff looks good to me and I don't expect any failures.

We probably should have 6 copies of zlib in the tree, all of slightly
different version.

Fixes PR toolchain/59413.
