./xbps-src bootstrap fixes
https://github.com/void-linux/void-packages/pull/21226

Description:
I found a few missing/broken things while testing `./xbps-src bootstrap`:

1. `bootstrap` requires texinfo on the host.
2. glibc doesn't contain usr/share/info.
3. m4 was broken.

Closes #21163 . Thanks to @rovenmaccorp
