Bootstrap fails on v0.7 master with failure to load stdlib packages

[jmert]

As of 0.7.0-alpha.198 (commit b331c70), I cannot build the system image; I suspect this has to do with the fact that I'm doing an out-of-tree build (specifically at julia/build where julia is the root of the git checkout) combined with the changes from PR #27633 (I'm guessing this line) — i.e.

$ cd $JULIA_GIT_DIR
$ cd usr/bin
$ ls ../../stdlib

$ cd -
$ cd build/usr/bin
$ ls ../../stdlib
ls: cannot access '../../stdlib': No such file or directory

(Sys.BINDIR on my other computer where I haven't yet tried recompiling does show that it points to the build/usr/bin path.)

Ugh. It's so annoying to give a better value there but sure.

Does this patch fix the issue?

It does.

Ok, I'll make a PR to change it. Thanks for reporting the failure!
