```
stage2: improved glibc stubs

This commit upgrades glibc shared library stub-creating code to use the
new abilists file which is generated by the new glibc-abi-tool project:
https://github.com/ziglang/glibc-abi-tool/

The abilists file is different in these ways:
 * It additionally encodes whether a symbol is a function or an object,
   and if it is an object, it additionally encodes the size in bytes.
 * It additionally encodes migrations of symbols from one library to
   another between glibc versions.
 * It is binary data instead of ascii.
 * It is one file instead of three.
 * It is 165 KB instead of 200 KB.

This solves three bugs:

Fixes #7667
Fixes #8714
Fixes #8896

```
