Comment (by Thomas Miedema <thomasmiedema@…>):

 In [changeset:"3340fe01bc6842c2cad53271541dce6699512ce0/ghc"
 3340fe01/ghc]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="3340fe01bc6842c2cad53271541dce6699512ce0"
 Build system: fix `make -j1` (#10973)

 There are multiple hacks all over the build system to account for the
 fact that the ghc package uses different build subdirectories
 (stage1/stage2) than the other packages (dist/dist-install).

 One such hack filtered on 'ghc%', with the intention of filtering the
 ghc package only. After renaming bin-package-db to ghc-boot
 (d2f9972a35ce05ceb8a78893e433ef1df06f73ef, Phab:D1313, #10796), ghc-boot
 also got caught in the hack, which broke the build when running without
 parallelism.

 This patch replaces the before mentioned hack by a different one, such
 that filtering on 'ghc%' is no longer necessary. See Note [inconsistent
 distdirs].
