Comment (by edsko):

 In the case of `sh validate` this happens when the validate script calls

 {{{
 $make binary-dist-prep
 }}}

 which it only does if you don't specify `FAST`, which might be why the OP
 was able to run validate. Tracking this down further, it gets stuck on:

 {{{
 # make -r --no-print-directory -f ghc.mk bindist BINDIST=YES
 "cp" -p ghc/stage1/build/tmp/ inplace/lib/bin/ghc-stage1
 cp: ghc/stage1/build/tmp/ is a directory (not copied).
 make: *** [inplace/lib/bin/ghc-stage1] Error 1
 }}}


 This particular `cp` command comes from the following rule in `build-
 prog.mk`:

 {{{
 # INPLACE_BIN might be empty if we're distcleaning
 ifeq "$(findstring clean,$(MAKECMDGOALS))" ""
 ifeq "$$($1_$2_INSTALL_INPLACE)" "YES"
 $$($1_$2_INPLACE) : $1/$2/build/tmp/$$($1_$2_PROG_INPLACE) | $$$$(dir
 $$$$@)/.
         "$$(CP)" -p $$< $$@
 endif
 endif
 }}}

 (lines 294-300). At this point somebody more familiar with the build
 system might have some idea?
