Comment (by pkubaj):

 Running {{{make install}}} on powerpc64 throws error:
 {{{ghc-cabal: '/usr/local/lib/ghc-8.6.3/bin/ghc-pkg' exited with an error:
 array-0.5.3.0: Warning: haddock-interfaces:
 /usr/local/share/doc/ghc-8.6.3/html/libraries/array-0.5.3.0/array.haddock
 doesn't exist or isn't a file
 array-0.5.3.0: dependency "base-4.12.0.0" doesn't exist (use --force to
 override)}}}

 Still, {{{ghc}}} binary was installed, and it works.

 When i had {{{DYNAMIC_GHC_PROGRAMS=YES}}}, I used the script from
 {{{bin/ghc}}}, but it threw the same error. It works with it disabled.

 When {{{DYNAMIC_GHC_PROGRAMS=YES}}}, {{{inplace/bin/ghc-stage2}}} is not
 present. {{{ghc-stage2}}} is in {{{ghc/stage2/build/tmp}}}:
 {{{
 root at talos:$/home/pkubaj/ghc-8.6.3-boot$ find . -name ghc-stage2
 ./ghc/stage2/build/tmp/ghc-stage2
 }}}

 This binary seems to run ok.


 {{{
