libgcc: Disable building shared objects ?

[Georg-Johann Lay]

For avr, there is no support for shared objects, yet
when building libgcc, for each module.o there is also module_s.o
that's build with -DSHARED.

How can this be turned off?

What doesn't word is to configure with --disable-shared, and even
without turning it off by hand, there is no use for module_s.o stuff.

These objects are just boosting the build time for the > 60 multilib
variants by 100%.

What also doesn't work it to set libgcc-s-objects to empty in t-avr.

Thanks, Johann
