Users of GNU ld (BFD) from binutils 2.39+ will observe multiple instances of a new warning when linking barebox and PBL in the form: ld: warning: defaultenv/defaultenv-2-dfu.bbenv.o: missing .note.GNU-stack section implies executable stack ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker ld: warning: .tmp_barebox1 has a LOAD segment with RWX permissions We don't need executable stack, so disable with -z noexecstack. We also do not use the permissions from ELF segments, so disable the warning with --no-warn-rwx-segments.
