[binutils-gdb] objcopy: Add --update-section option.


*** TEST RESULTS FOR COMMIT acf1419f9c52d06ee70169b85c5f8980c7359f8f ***

Commit: acf1419f9c52d06ee70169b85c5f8980c7359f8f

objcopy: Add --update-section option.
New option for objcopy --update-section allows the contents of a section
to be updated while maintaining the section flags, and, for ELF files,
the section to segment mapping.

New test uses --dump-section and --update-section to check that a
section can be made larger and smaller with an update.
