[OE-core] [PATCH] Revert "flex: upgrade to 2.6.2"

This reverts commit 3632abd01abb8dfff230e18f828af705da488f97.
Multiple people have expressed issues with flex-2.6.2; personally I had
problems compiling libsepol from meta-selinux (for libselinux). I tried
upgrading to flex-2.6.3, but that caused binutils-cross_2.27 to fail.
The simplest for now is to downgrade to flex-2.6.0.

-Subject: [PATCH] build: support cross compiling
-
-Check for cross compiling. If cross compiling, build stage1flex using a
-custom link command.
-We also override LDADD since that adds the replacement implementations
-that are cross compiled, and instead always use the replacement library
-implementations.
-
-We don't use BUILD_OBJEXT and BUILD_EXEEXT since it seems that automake
-does not support these.
-
-Fixes #78.

-+# SYNOPSIS
-+#
-+# AX_PROG_CC_FOR_BUILD
-+#
-+# DESCRIPTION
-+#
-+# This macro searches for a C compiler that generates native executables,
-+# that is a C compiler that surely is not a cross-compiler. This can be
-+# useful if you have to generate source code at compile-time like for
-+# example GCC does.
-+#
-+# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
-+# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
-+# The value of these variables can be overridden by the user by specifying
-+# a compiler with an environment variable (like you do for standard CC).
-+#
-+# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
-+# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
-+# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
-+# substituted in the Makefile.
