Makefile.inc: objcopy extracts a wrong section of cbfs_master_header
Commit 75226bb879837 ("Makefile.inc: Generate master header and pointer
as C structs") may cause objcopy to copy a wrong section of object file
resulting in miscompiled image with missing CBFS master header. This
makes the usage of secondary payloads impossible.
For example a wrong section for CONFIG_ANY_TOOLCHAIN +
objcopy 2.38-slack151 will copy ".note.gnu.property".
This patch constraints the sections to .data and .bss only.
