So I tried with the exact same paths and it worked for me:
$ mkdir -p /local/lnx/next/linux-next-20140606
$ git archive d4bc590f8716f7dde6b7bca319097ac30a8cb0b4 | tar xf - -C
/local/lnx/next/linux-next-20140606/
$ cd /local/lnx/next/linux-next-20140606/
$ make ARCH=um SUBARCH=i386 O=/tmp/O defconfig
$ make ARCH=um SUBARCH=i386 V=1 O=/tmp/O

and it worked.

Here, it should do

/bin/sh
'/local/lnx/next/linux-next-20140606/arch/x86/syscalls/syscallhdr.sh'
'/local/lnx/next/linux-next-20140606/arch/x86/syscalls/syscall_32.tbl'
'arch/x86/syscalls/../include/generated/uapi/asm/unistd_32.h' 'i386' '' ''
/bin/sh
'/local/lnx/next/linux-next-20140606/arch/x86/syscalls/syscallhdr.sh'
'/local/lnx/next/linux-next-20140606/arch/x86/syscalls/syscall_64.tbl'
'arch/x86/syscalls/../include/generated/uapi/asm/unistd_64.h'
'common,64' '' ''
/bin/sh
'/local/lnx/next/linux-next-20140606/arch/x86/syscalls/syscallhdr.sh'
'/local/lnx/next/linux-next-20140606/arch/x86/syscalls/syscall_64.tbl'
'arch/x86/syscalls/../include/generated/uapi/asm/unistd_x32.h'
'common,x32' '' '__X32_SYSCALL_BIT'
/bin/sh
'/local/lnx/next/linux-next-20140606/arch/x86/syscalls/syscalltbl.sh'
/local/lnx/next/linux-next-20140606/arch/x86/syscalls/syscall_32.tbl
arch/x86/syscalls/../include/generated/asm/syscalls_32.h

which is not happening in your case for some reason. Can you please
check if you have some stale files in include/generated in the *source*
tree?

git ls-file -o --directory

It could be that there is some include/generated directory from a
previous in-tree build.
