This should fix CI which is failing lately like this:
https://cirrus-ci.com/task/4665005218463744
ld-elf.so.1: /lib/libc.so.7: version FBSD_1.8 required by
/usr/local/bin/stack not found
This is a first step to split up the cabal and stack caches in separate
pieces. Here we split the work folder, which just contains the
postgrest-specific build artifacts, into a separate cache.
More fine-grained caching should give us better cache hits and much
fewer upload size in the regular case, improving CI performance.
Since the work file caches are very small (about 30-40 MB) they are
cached for PRs, too. This will allow the majority of PRs, which only
change source code files, but no dependencies, to still have cached
their build files for additional commits.
This now behaves similar to other CI build jobs, which always run on the
main branches, but only conditionally on PRs, depending on which files
changed.
By passing -split-sections to all dependencies, GHC will link only the
modules we actually use and not the full package for each dependency.
This does neither work on MacOS nor Windows, thus we don't do it for
stack right now.
Stripping unused symbols in CI will further decrease the size of those files.
