At level 34 the added functions are:

<stdio_ext.h>
__freadahead

<string.h>
memset_explicit

<spawn.h>
posix_spawn_file_actions_addchdir_np
posix_spawn_file_actions_addfchdir_np

<unistd.h>
copy_file_range
close_range

Here are the corresponding adjustments in Gnulib.

	Resolve conflicts for functions introduced in Android API level 34.

	* m4/copy-file-range.m4 (gl_FUNC_COPY_FILE_RANGE): On platforms without
	glibc, test for copy_file_range using gl_CHECK_FUNCS_ANDROID instead of
	AC_CHECK_FUNCS_ONCE. Conditionally set REPLACE_COPY_FILE_RANGE.
	* doc/glibc-functions/copy_file_range.texi: Mention the Android API
	levels.

	* m4/posix_spawn.m4 (gl_POSIX_SPAWN_BODY): Test for
	posix_spawn_file_actions_addchdir_np and
	posix_spawn_file_actions_addfchdir_np using gl_CHECK_FUNCS_ANDROID
	instead of AC_CHECK_FUNCS_ONCE.
	* m4/posix_spawn_faction_addchdir.m4
	(gl_FUNC_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR): Test for
	posix_spawn_file_actions_addchdir_np using gl_CHECK_FUNCS_ANDROID
	instead of AC_CHECK_FUNCS_ONCE.
	* m4/posix_spawn_faction_addfchdir.m4
	(gl_FUNC_POSIX_SPAWN_FILE_ACTIONS_ADDFCHDIR): Test for
	posix_spawn_file_actions_addfchdir_np using gl_CHECK_FUNCS_ANDROID
	instead of AC_CHECK_FUNCS_ONCE.
	* doc/glibc-functions/posix_spawn_file_actions_addchdir_np.texi: Mention
	the Android API levels.
	* doc/glibc-functions/posix_spawn_file_actions_addfchdir_np.texi:
	Likewise.

	* lib/string.in.h (memset_explicit): Consider REPLACE_MEMSET_EXPLICIT.
	* m4/string_h.m4 (gl_STRING_H_DEFAULTS): Initialize
	REPLACE_MEMSET_EXPLICIT.
	* modules/string (Makefile.am): Substitute REPLACE_MEMSET_EXPLICIT.
	* m4/memset_explicit.m4 (gl_FUNC_MEMSET_EXPLICIT): Test for
	memset_explicit using gl_CHECK_FUNCS_ANDROID instead of
	AC_CHECK_FUNCS_ONCE. Conditionally set REPLACE_MEMSET_EXPLICIT.
	* modules/memset_explicit (configure.ac): Consider
	REPLACE_MEMSET_EXPLICIT.
	* doc/posix-functions/memset_explicit.texi: Mention the Android API
	levels.

	* m4/freadahead.m4 (gl_FUNC_FREADAHEAD): Test for __freadahead using
	gl_CHECK_FUNCS_ANDROID instead of AC_CHECK_FUNCS_ONCE.
	* lib/freadahead.h: Update comment.
