libtool defaults to filtering flags passed at link-time.
This brings the filtering in GCC's 'fork' of libtool into sync with
upstream libtool commit 22a7e547e9857fc94fe5bc7c921d9a4b49c09f8e.
In particular, this now allows some harmless diagnostic flags (especially
useful for things like -Werror=odr), more optimization flags, and some
Clang-specific options.
GCC's -flto documentation mentions:
> To use the link-time optimizer, -flto and optimization options should be
> specified at compile time and during the final link. It is recommended
> that you compile all the files participating in the same link with the
> same options and also specify those options at link time.
This allows compliance with that.

Port to hosts whose 'sort' and 'tail' implementations
treat operands with leading '+' as file names, as POSIX
has required since 2001. However, make sure the code still
works on pre-POSIX hosts.
* ltmain.sh: Don't assume "sort +2" is equivalent to
"sort -k 3", since POSIX 1003.1-2001 no longer requires this.
contrib:
* compare_tests: Don't assume "sort +2" is equivalent to
"sort -k 3", since POSIX 1003.1-2001 no longer requires this.
gcc:
* Makefile.in (slowcompare): Port to POSIX 1003.1-2001,
which says you should use "tail -c +N" rather than "tail +Nc".
Fix a bug: the old code incorrectly skipped 15 bytes, not 16.
