PR target/65038
	* config.in: Regenerated.
	* configure: Likewise.
	* configure.ac (AC_HEADER_STDC): Add explicit.
	(AC_CHECK_HEADERS): Check for default headers
	plus for ftw.h one.
	* libgcov-util.c (gcov_read_profile_dir): Disable use
	of ftw-function, if header not found.
	(ftw_read_file): Don't translate if ftw header isn't
	present.
