support -blazy, add option to disable

I suggest exportinitfini_flag is enabled by default or atleast for the build of
libstdc++.a and libgcc_s.a.
It should have minimal impact/risk.

initdependents_flag has risk/impact attached. You may want to reverse the
default.

My case for having it on by default:
To use exceptions within global constructors a module needs to be linked with
initdependents_flag enabled.

I believe there are other functions in libstdc++ that depend on initialization
order. I do not have specifics.

Assuming AIX was the only OS that works this way, it allows removal of these
types of workarounds:
