In e72403f96d, we added the flag
"--no-dynamicbase" for disabling the dynamicbase flag which we set
by default. At the time, ld.bfd didn't have any corresponding
option (as ld.bfd defaulted to not setting the flag). Almost at
the same time, corresponding options were added to ld.bfd for
disabling it (while it was being enabled by default), with a
different name, "--disable-dynamicbase".
Thus add the "--disable-dynamicbase" option. Make this default
one advertised in the help listing, but keep the "--no-dynamicbase"
form as an alias. Also improve checking for the last option set
if there are multiple ones on the same command line.
Also add corresponding disable options for a lot of other flags
that we set by default, also added in ld.bfd in the same commit:
