Fix #73219 (fix acinclude when / is present)

Remove Netware support

If this does not break the Unix system somehow, I'll be amazed. This should get most of it out, apologies for any errors this may cause on non-Windows ends which I can

Ship AX_CHECK_COMPILE_FLAG in a separate file to preserve its license.

In commit 086f9ad, I added a new macro AX_CHECK_COMPILE_FLAG from the
autoconf archive. Jakub Zelenka pointed out that the license of the
macro (GPL-3+ with exception) does not agree with the license of PHP
itself (PHP-3.01). We should therefore ship the macro in a separate
file with its own license header. That is allowed and is done for
many other files in the PHP repository.

This commit adds a new top-level "m4" directory and places the
upstream ax_check_compile_flag.m4 file in it. The macro is no longer
inlined; instead, our acinclude.m4 now includes the aforementioned
file with m4_include.

Use AX_CHECK_COMPILE_FLAG macro to check for -fvisibility=hidden support.

The existing check for -fvisibility=hidden support came from a time
when only GCC had it. The test for it used a regular expression to
parse the GCC major version from the output of `$CC --version`, and
would look for version 4 or greater.

The regular expression used to accomplish this is doomed, however,
since GCC can be built with a custom version string
(--with-pkgversion). Moreover, the $CC variable can be set to
something that confuses it but is otherwise valid. For example, it
would fail with CC=x86_64-pc-linux-gnu-gcc.

This commit fixes two aspects of the feature test. First, it no longer
limits the test to GCC. At least clang now supports the flag, and can
make use of it when GCC is its backend. Second, support for the flag
is tested directly, by attempting to pass it to the compiler, rather
than by parsing its version string. The latter is accomplished with a
new macro, AX_CHECK_COMPILE_FLAG, taken from the autoconf archive.
The new macro has been added to acinclude.m4, and the test stanza in
configure.in has been replaced with a single call to the new macro.

Note that the new macro calls AC_PREREQ(2.64) -- a more stringent
requirement than the existing AC_PREREQ(2.59) in configure.in. The
difference represents about six years of autoconf releases, from v2.59
in December of 2003 to v2.64 in July of 2009.

This problem was noticed by Brian Evans, who also suggested the fix.
