issue building libgcc 7.3 on Snow Leopard

[Riccardo Mottola]

Hi,

I fail to build libgcc 7.3 on Snow Leopard.

This issue:

https://trac.macports.org/ticket/55302

still applies. I noticed that the Portifile was I updated, I tried to 
manually apply the same fix I used last time, but no help.

checking for j0f... no
checking for j0...

interesting thaat it happens at "checking for j0"

how is it for you? can you reproduce? on the buildfarm?

Thank you,
