[PATCH] objtool: Make 'sec-address' always on

[Christophe Leroy]

Most of the time objtool warnings are useless without the
absolute address within the section.

Today there is --sec-address option to get it printed, but
that option is nowhere used and requires a change in Makefile
to use it.

Having the address inside the section at all time in addition
to the address within the object doesn't hurt and will help.

Remove the --sec-address option and print it at all time.
