10Subject: [PATCH] build: support cross compiling
11
12Check for cross compiling. If cross compiling, build stage1flex using a
13custom link command.
14We also override LDADD since that adds the replacement implementations
15that are cross compiled, and instead always use the replacement library
16implementations.
17
18We don't use BUILD_OBJEXT and BUILD_EXEEXT since it seems that automake
19does not support these.
20
21Fixes #78.

63+# SYNOPSIS
64+#
65+# AX_PROG_CC_FOR_BUILD
66+#
67+# DESCRIPTION
68+#
69+# This macro searches for a C compiler that generates native executables,
70+# that is a C compiler that surely is not a cross-compiler. This can be
71+# useful if you have to generate source code at compile-time like for
72+# example GCC does.
73+#
74+# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
75+# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
76+# The value of these variables can be overridden by the user by specifying
77+# a compiler with an environment variable (like you do for standard CC).
78+#
79+# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
80+# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
81+# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
82+# substituted in the Makefile.
