-# Note that -march is not among compiler options in below linux-armv4
-# target line. Not specifying one is intentional to give you choice to:
-#
-# a) rely on your compiler default by not specifying one;
-# b) specify your target platform explicitly for optimal performance,
-#    e.g. -march=armv6 or -march=armv7-a;
-# c) build "universal" binary that targets *range* of platforms by
-#    specifying minimum and maximum supported architecture;
-#
-# As for c) option. It actually makes no sense to specify maximum to be
-# less than ARMv7, because it's the least requirement for run-time
-# switch between platform-specific code paths. And without run-time
-# switch performance would be equivalent to one for minimum. Secondly,
-# there are some natural limitations that you'd have to accept and
-# respect. Most notably you can *not* build "universal" binary for
-# big-endian platform. This is because ARMv7 processor always picks
-# instructions in little-endian order. Another similar limitation is
-# that -mthumb can't "cross" -march=armv6t2 boundary, because that's
-# where it became Thumb-2. Well, this limitation is a bit artificial,
-# because it's not really impossible, but it's deemed too tricky to
-# support. And of course you have to be sure that your binutils are
-# actually up to the task of handling maximum target platform. With all
-# this in mind here is an example of how to configure "universal" build:

+        # you choice to:
+        #
+        # a) rely on your compiler default by not specifying one;
+        # b) specify your target platform explicitly for optimal
+        # performance, e.g. -march=armv6 or -march=armv7-a;
+        # c) build "universal" binary that targets *range* of platforms
+        # by specifying minimum and maximum supported architecture;
+        #
+        # As for c) option. It actually makes no sense to specify
+        # maximum to be less than ARMv7, because it's the least
+        # requirement for run-time switch between platform-specific
+        # code paths. And without run-time switch performance would be
+        # equivalent to one for minimum. Secondly, there are some
+        # natural limitations that you'd have to accept and respect.
+        # Most notably you can *not* build "universal" binary for
+        # big-endian platform. This is because ARMv7 processor always
+        # picks instructions in little-endian order. Another similar
+        # limitation is that -mthumb can't "cross" -march=armv6t2
+        # boundary, because that's where it became Thumb-2. Well, this
+        # limitation is a bit artificial, because it's not really
+        # impossible, but it's deemed too tricky to support. And of
