Bug#964824: hdevtools: FTBFS with GHC 8.8

[Sebastian Ramacher]

Source: hdevtools
Version: 0.1.8.0-1
Severity: serious
Tags: ftbfs sid bullseye
Justification: fails to build from source (but built successfully in the past)

hdevtools currently fails to build:
| [ 4 of 14] Compiling Info             ( src/Info.hs, dist-ghc/build/hdevtools/hdevtools-tmp/Info.o )

|       In the expression:
