This isn't the correct fix. Unfortunately it's a bit more complicated than that.
USE_PKGSRC_GCC_RUNTIME is a user variable, so packages shouldn't be setting it. Its purpose is to determine whether the dependency for GCC libraries should come from the -libs package instead of the main GCC package.
The problem is that the main GCC packages only set DEPMETHOD=build, which in the case of USE_PKGSRC_GCC_RUNTIME=no is wrong, they should be full dependencies so that the runtime libraries are available.
I'll need to do some testing before making changes, as it's been a while since I used the in-tree GCC packages (mostly because they have issues such as this).
We should also consider just making USE_PKGSRC_GCC_RUNTIME=yes the default.
