user/guile: refactor APKBUILD to use our own bootstrapped interpreter/compiler
Guile ships with pre-built binaries for its interpreter and compiler. This saves time when building the package from source. However on 32-bit ppc, they are broken and need to be regenerated (bootstrapped).
For consistency, we should generate these for all architectures, but should not require every user or developer to waste time doing so. Only maintainers who bump this package will have to pay this cost.
This ticket is to complete the following:
- Investigate whether these binaries can be safely cross-compiled. It may be too inconvenient to have to do this manually on multiple builders.
- Create a
maintain
script or similar which produces tarball(s) suitable for hosting on distfiles. - Modify the
APKBUILD
to pull those tarball(s) and build the package as normal.
