Patches dropped as they are merged upstream:
- CVE-2016-6354.patch
- 0002-avoid-c-comments-in-c-code-fails-with-gcc-6.patch
- do_not_create_pdf_doc.patch
Apply a patch from github to simplify cross-compilation and not need a
flex-native to bootstrap.

+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.
