Comment (by ru0mad):

 Hello,

 I managed somehow to build ghc-8.4.2 on solaris 11.4 (x86_64), along with
 cabal-install and finally stack.

 I had to apply some patches :
  - to workaround the file locking problem (flock() missing on solaris) :
    * in ghc to catch the FileLockingNotSupported exception raised on
 solaris by GHC.IO.Handle.Lock
    * similar in cabal-install (which clones more or less the GHC code)
    * patch in filelock (used by stack) to refer to the file locking from
 GHC base
  - to have a working building process (the -optl-optl problem + )
  - to include <termios.h> in stack where needed (in unix/Terminal.hsc)

 As file locking is made a no-op, concurrent acces to package db should be
 broken, but so far I didn't have any problem on my standalone solaris box.

 Some tests are failing, but most of it seems quite innocuous (mostly
 differences in output) but some are more preoccupying, yet it sort of
 works (test summary attached).

 The patches and building scripts are attached (for ghc, cabal-install,
 stack).

 As I'm not very experimented in this, I would be very interested to know
 if the tweaks I applied still make a workable version or if it is totally
 borked.

 Bruno
