flex currently leaks the path of m4 as found on the build host.
While it is possible to override this using the M4 environment
variable (which we always did for autotools based builds) when
using CMake or Ninja the M4 variable is not set.
One easy fix is to make flex take STAGING_DIR_HOST into account
and expect m4 there if that variable is set in the environment.

Instead of editing the SUBDIRS variable with a patch,
it can be overriden at the end of the command line when invoking Make.
Skip the build for po files as well, which is causing a conflict
depending on the version of gettext detected, and macros present.

Some packages like libpfring assume the presense of lex, which on some
other systems is a symlink to flex but not all. Symlink flex to fix
compilation.
Arch Linux and Fedora do this as far as I know.

Fix segmentation fault caused by implicit declaration of function 'reallocarray'. Added patch will enable
reallocarray() prototype in glibc 2.26+ on Linux systems. This fix will be included in flex 2.6.5.

This was already done in commit 91e262c6b3 ("tools: flex: fix build
with automake 1.15.1")

After the update of GNU automake, the flex configure fails with
configure.ac:31: error: version mismatch. This is Automake 1.15.1,
configure.ac:31: but the definition used by this AM_INIT_AUTOMAKE
configure.ac:31: comes from Automake 1.15.
Apply the autoreconf host fixup to properly regenerate configure before
to avoid triggering the version mismatch. Also refresh the patch while
we're at it.
Fixes FS#885.

Update flex to 2.6.1
* Flex has moved to Github, adjust download link
* Remove patch that has been applied upstream
* Disable building tests to avoid circular dependency to bison
- disable also docs and examples at the same time
