Discussion ensued, ending in the following comment:

[6:34 PM] BertalanD: I guess we can try partially reverting this
[6:34 PM] BertalanD: 738e52d (edited)
[6:35 PM] BertalanD: only the AS_NEEDED part though. Setting -lgcc_s in LINK_SPEC is a dirty hax

It was suggested an issue be submitted, so in the name of posterity in all their majesty...
