linux-libc-headers: Add big warning about antisocial behaviour
I'm getting concerned with the number of people forking this recipe and not understanding what they're doing. I'm therefore proposing adding in a suitable warning to people thinking of copying it. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

+#
+# You're probably looking here thinking you need to create some new copy
+# of linux-libc-headers since you have your own custom kernel. To put
+# this simply, you DO NOT.
+#
+# Why? These headers are used to build the libc. If you customise the
+# headers you are customising the libc and the libc becomes machine
+# specific. Most people do not add custom libc extensions to the kernel
+# and have a machine specific libc.
+#
+# But you have some kernel headers you need for some driver? That is fine
+# but get them from STAGING_KERNEL_DIR where the kernel installs itself.
+# This will make the package using them machine specific but this is much
+# better than having a maching specific C library. This does mean your
+# recipe needs a DEPENDS += "virtual/kernel" but again, that is fine and
+# makes total sense.
+#
+# There can also be a case where your kernel extremely old and you want
+# an older libc ABI for that old kernel. The headers installed by this
+# recipe should still be a standard mainline kernel, not your own custom
+# one.
