Notes for ghc - reproducible builds result

Version annotated: 7.10.3-9
Identified issues:
Identifier: blacklisted_on_jenkins_armhf_only
Description Some packages have been blacklisted only on armhf in our test infrastructure
because their builds take too long on the tiny armhf boards we're using.
The mitigation against this is to add more architectures or to wait until
we test against the debian archive, when it will become sensible to raise
the 18h timeout for a single build.
Until his happens, please rely on the amd64, i386 and arm64 tests.
Identifier: captures_build_path
Description Captures build path, e.g., /build/1st/foo-42.0 v. /build/foo-42.0/2nd
.
Until early 2024 we varied the build path when testing packages from unstable
and experimental, which we have stopped doing now as the build path is recorded
as part of the environment and thus can be used when rebuilding.
.
This issue is kept here for the time being.
.
This issue is only for miscellaneous issues which need individual fixes,
please create new issues for specific issues, e.g. gcc_captures_build_path.
.
Here follows some general tips for packages using the standard GNU toolchain:
.
If using autoconf, make sure you call ./configure via a relative and not absolute path.
.
If your issue is related to using the `__FILE__` macro, or the recording of
--debug-prefix-map flags in non-GCC non-debugging output, this is what is
fixed by our patch mentioned above; you should not need to fix it
specifically in your package.

Comments: Appears to be a readdir() dependency: find(1) finds a file under two different
names, ghc/ghc.txt and ghc-$(VERSION)/ghc.txt, due to a symlink:
