+[ARM] 4600/1: fix kernel build failure with build-id-supporting binutils
+
+Newer versions of binutils support --build-id, which adds an ELF
+note section called ".note.gnu.build-id" to the output.  On the ARM
+kernel build, because there is no explicit mention of this section
+in the shipped ld script, this section is placed at vaddr 0x00000000
+(whereas the normal kernel text/data typically starts at vaddr
+0xc0008000), causing the output of objcopy (Image) to produce a 3G+
+file.
+
+This patch makes objcopy strip the .note.gnu.build-id section from
+the Image file along with all other note sections, which fixes the
+build.
