   7 [ARM] 4600/1: fix kernel build failure with build-id-supporting binutils
   8
   9 Newer versions of binutils support --build-id, which adds an ELF
  10 note section called ".note.gnu.build-id" to the output.  On the ARM
  11 kernel build, because there is no explicit mention of this section
  12 in the shipped ld script, this section is placed at vaddr 0x00000000
  13 (whereas the normal kernel text/data typically starts at vaddr
  14 0xc0008000), causing the output of objcopy (Image) to produce a 3G+
  15 file.
  16
  17 This patch makes objcopy strip the .note.gnu.build-id section from
  18 the Image file along with all other note sections, which fixes the
  19 build.
