Comment (by kgardas):

 I've done simple test and where the compilation failed with the error
 above I've replaced -split-objs with -split-sections and repeated the step
 and then continue with `gmake`. This way I've been able to build GHC HEAD
 on Solaris 11.2 but only with patch below applied. I guess nobody test on
 Solaris so no-flock condition is kind of broken, the error is:
 {{{
 libraries/base/GHC/IO/Handle/Lock.hsc:159:20: error:
     <80>� Variable not in scope:
         throwIO :: FileLockingNotSupported -> IO Bool
     <80>� Perhaps you meant <80><98>throw<80><99> (imported from
 GHC.Exception)

     |                    ^^^^^^^
 gmake[1]: *** [libraries/base/dist-install/build/GHC/IO/Handle/Lock.o]
 Error 1
 }}}
 and my naive patch is:
 {{{
