Comment (by maeder):

 It has nothing do to with
 libraries/Cabal/Cabal/Distribution/Simple/Program/Script.hs (although
 being wrong, too), but is caused by "$$($1_$2_BINDIST_WRAPPER)" in rules
 /shell-wrapper.mk. The variable $(SHELL) is not the one set by
 ./configure.

 prependLibraryPath from rules/library-path.mk creates the non-Bourne
 export statement.
