see https://ghc.haskell.org/trac/ghc/ticket/8783 how this issue may be
solved. Any (or both) of the two proposed patches work for me.

Definitely use this, FreeBSD (for example) does not ship with bash so
/bin/bash will *not* exist.
Please, do not introduce dependency on bash unless it is really
necessary.
In fact ./configure detects "/bin/bash" as SHELL under Solaris, so this
setting could be used (instead of hard coding "bin/sh")!
(Under FreeBSD a proper other SHELL might be found by ./configure.)
Many configure files of libraries also set SHELL this way.
Yet, for this ghc-pwd-bindist script it is easier to make the script
(Bourne) /bin/sh compatible. Yet, I have not found out, how this script
is created!
utils/ghc-pwd/ghc.mk contains
"utils/ghc-pwd_dist-install_WANT_BINDIST_WRAPPER = YES"
but then I'm lost what build-prog does from rules/build-prog.mk.
Maybe somehow the code in
libraries/Cabal/Cabal/Distribution/Simple/Program/Script.hs is called,
then the second line should be changed from:
setEnv (var, Nothing) = ["unset " ++ var, "export " ++ var]
setEnv (var, Just val) = ["export " ++ var ++ "=" ++ quote val]
to:
setEnv (var, Nothing) = ["unset " ++ var, "export " ++ var]
setEnv (var, Just val) = [var ++ "=" ++ quote val, "export " ++ var]
I guess that is still POSIX compliant.
Cheers Christian
