GHC HEAD now needs extra tools to build libffi?

[Thomas Jakway]

Anyone else getting linker errors?

This is after running

make clean && make distclean && find . -name "*.o" -type f -delete && 
find . -name "*.hi" -type f -delete

then

./boot && ./configure && make -j5

(ghc-new is not a new checkout, this error is happening on a branch I'm 
working on, but one that doesn't touch the FFI)
