Fix: ASAN build does not link

When building an ASAN build, I get this link error currently:
```
ld.lld: error: version script assignment of 'global' to symbol '__progname' failed: symbol not defined
ld.lld: error: version script assignment of 'global' to symbol 'environ' failed: symbol not defined
```

The solution (as proposed by Brecht) is to change the symbol names into patterns with a wildcard.
That way the linker does not fail when the symbols are not found.
