libgcc depends on itself, which breaks gcc13

[barracuda156]

This is what, apparently, made impossible to try installing gcc13:

That doesn't make sense. The libgcc Portfile has a single depends_lib statement which doesn't do an -append so there is no way that it could ever generate a double dependency itself.

I cannot reproduce this, neither with 2.7.1 nor 2.10.x nor after adding an up-to-date compilers-1.0 PG to MacStrop. Do you have any local modifications that add a port:libgcc dependency?

Should not be, but let me think. Ports and PGs in lnxports and macstrop are untouched, with the exception of sorting libiconv and isl issues here: https://github.com/barracuda156/lnxports (I cannot see how this could possibly affect libgcc dependencies, and also this is a new commit, while I had this dependency error from the get-go).

I have probably set the base to prefer gcc for riscv64; that probably should not have introduced a dependency cycle. After all, I do not get it on powerpc, where gcc is preferred.

Doh, I don't know how I overlooked the culprit this morning!

Hmm, something does not work for me still:
