PR libstdc++/8610
* acinclude.m4 (GLIBCXX_CHECK_INT64_T): New macro,
checking for the availability of int64_t.
(GLIBCXX_CHECK_LFS): New macro, checking for LFS support.
* configure.ac: Call here.
* acconfig.h: Add undef for the corresponding symbols.
* config/io/basic_file_stdio.cc (__basic_file<char>::open):
Depending on _GLIBCXX_USE_LFS, call fopen64 or fopen.
(__basic_file<char>::seekoff): Likewise, call lseek64 when
available, otherwise lseek, checking the __off parameter.
* include/bits/postypes.h: Typedef __streamoff_base_type
to int64_t if available, otherwise long long.
* aclocal.m4: Regenerate.
* config.h.in: Likewise.
* configure: Likewise.
* acinclude.m4 (GLIBCXX_CHECK_POLL, GLIBCXX_CHECK_WRITEV):
Use AC_TRY_LINK instead of AC_TRY_COMPILE.
