grub: Backport fix to work with new binutils
New versions of binutils caused object files to be 128MB in size, backporting this fix reduced them back to a sensible size, e.g. 1024 bytes. This avoids initramfix size issues! Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

+Subject: build: Fix GRUB i386-pc build with Ubuntu gcc
+
+With recent versions of gcc on Ubuntu a very large lzma_decompress.img file is
+output. (e.g. 134479600 bytes instead of 2864.) This causes grub-mkimage to
+fail with: "error: Decompressor is too big."
+
+This seems to be caused by a section .note.gnu.property that is placed at an
+offset such that objcopy needs to pad the img file with zeros.
+
+This issue is present on:
+Ubuntu 19.10 with gcc (Ubuntu 8.3.0-26ubuntu1~19.10) 8.3.0
+Ubuntu 19.10 with gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008
+
+This issue is not present on:
+Ubuntu 19.10 with gcc (Ubuntu 7.5.0-3ubuntu1~19.10) 7.5.0
+RHEL 8.0 with gcc 8.3.1 20190507 (Red Hat 8.3.1-4)
+
+The issue can be fixed by removing the section using objcopy as shown in
+this patch.
