Subject: Use of uninitialized value %ENV of type Any in string context

This happens a lot at the moment. The issue has been around pre-curli but I think precompilation has exposed it a lot. So I'm making this ticket to focus on the general issue

1. Happens a lot in panda
==> Bootstrapping Panda
Use of uninitialized value %ENV of type Any in string context
Any of .^name, .perl, .gist, or .say can stringify undefined things, if needed.  in sub MAIN at bootstrap.pl:12
Use of uninitialized value %ENV of type Any in string context
...
==> Fetching Linenoise
Use of uninitialized value %ENV of type Any in string context
Any of .^name, .perl, .gist, or .say can stringify undefined things, if needed.  in sub git-fetch at /Users/llfourn/.rakudobrew/moar-nom/install/share/perl6/site/sources/66302B2E45F3ADCA25D8D7CCEF34037ECE91C096:46

2. Bug #126447 for perl6: [BUG] temp %*ENV bug

3. Bug #126840 for perl6: $*KERNEL and env lookup

4. Bug #126880 for perl6: [BUG] no precompilation with compile time warning dies painfully

It happens in CLONE-HASH-DECONTAINERIZED in core/control.pm, when %*ENV is cloned (usually in preparation for shelling out some command in qx// or something) when it has some dubious value.


The particular value related to precompilation that causes it is RAKUDO_PRECOMP_DIST
