build failure with 'make distcheck' without 'make' first

[Assaf Gordon]

Hello,

I noticed something strange, the following fails to build:

    $ make distclean ; ./configure ; make distcheck
    [...]
       CC       sed/sed_sed-compile.o
    In file included from sed/compile.c:20:

    make[1]: *** [sed/sed_sed-compile.o] Error 1
    make: *** [dist] Error 2


From a cursory look it seems building 'gnulib' is not a dependency of 
'distcheck'.

I'll investigate further tomorrow.
