- [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.
