- Rebase binutils-2.39-branch.diff.gz that contains fix for PR29451.

- Add binutils-2.39-branch.diff.gz.
- Explicitly enable --enable-warn-execstack=yes and --enable-warn-rwx-segments=yes.
- Add gprofng subpackage.

- Update to binutils 2.39:
* The ELF linker will now generate a warning message if the stack is made
executable. Similarly it will warn if the output binary contains a
segment with all three of the read, write and execute permission
bits set. These warnings are intended to help developers identify
programs which might be vulnerable to attack via these executable
memory regions.
The warnings are enabled by default but can be disabled via a command
line option. It is also possible to build a linker with the warnings
disabled, should that be necessary.
* The ELF linker now supports a --package-metadata option that allows
embedding a JSON payload in accordance to the Package Metadata
specification.
* In linker scripts it is now possible to use TYPE= in an output
section description to set the section type value.
* The objdump program now supports coloured/colored syntax
highlighting of its disassembler output for some architectures.
(Currently: AVR, RiscV, s390, x86, x86_64).
* The nm program now supports a --no-weak/-W option to make it ignore
weak symbols.
* The readelf and objdump programs now support a -wE option to prevent
them from attempting to access debuginfod servers when following
links.
* The objcopy program's --weaken, --weaken-symbol, and
