bug#61987: 'current-guix' uses configure flags of Git checkout

[Winter]

I've tried to dig deeper into this, but am stumped by an issue: editing 
'build-aux/build-self.scm' isn't actually doing anything.

After applying this diff, the status message still prints out when running 
'./pre-inst-env guix build -e "((@ (gnu packages package-management) 
current-guix))"':

diff --git a/build-aux/build-self.scm b/build-aux/build-self.scm

However, (guix channels) is definitely reading build-self, as changing the path 
it reads it from to a nonexistent path causes the build to throw, as expected.

The same goes for if I edit any module except for some values in (guix config) 
-- 'current-guix' never gets rebuilt.

I'd appreciate any help in figuring this out.

Thanks,
Winter
