New description:

 If I clone git HEAD and do:

 {{{
 perl boot && ./configure && make
 }}}

 The build fails with:

 {{{
 /usr/bin/ld: cannot find -lHSghc-boot-0.0.0.0
 collect2: error: ld returned 1 exit status
 }}}

 and after that point it keeps failing no matter what I do. Doing a `make
 clean` followed by `make -j<N>` with N >= 2 is fine.

 Akso building from scratch with:
 {{{
 perl boot && ./configure && make -j<N>
 }}}

 with N of 2 or more is fine.

 Looks like some sort of dependency problem.
