Build process loads ~/.juliarc.jl for julia-base-cache target

[iamed2]

Introduced in #24120

Looks like some options should be set after JULIA_EXECUTABLE, at least --startup-file=no and maybe more?

Good catch. As a breadcrumb to someone who wants to fix this, it should be as easy as

A test of some kind would be ideal but I'm not sure how best to do that.
