aports/community/ghc/0001-testsuite-Ensure-T5423-flushes-C-output-buffer.patch
Rémi Lefèvre 42336c1358 community/ghc: fix testsuite on Alpine Linux
- Add `MAKEFLAGS= ` hack to work around failing `+PYTHON`
- Add "stat too good" results for Alpine x64
- Increase tolerancy for two "stat not good enough" tests
- Add a few more patches from mainline
- Require gnu grep to fix T13340 & T7014
- Skip T2615 and T10458 (unresolved linking issues)

Some tests should be investigated, particularly
- T9630 (+22% memory allocation)
- T10458: linking issue
- T2615: linker script issue
- T12600: broken pipe with grep .. | head -n 1 (replaced by grep -m 1)

Hopefully we can get rid of the MAKEFLAGS hack once Hadrian is used.

Subject: testsuite: Ensure T5423 flushes C output buffer
Previously T5423 would fail to flush the printf output buffer.
Consequently it was platform-dependent whether the C or Haskell print
output would be emitted first.
