With regular +# libtool styled shared lib names, the linker would interfer and +# link against the shared lib variant even when GHC runs in -static +# mode. +# 2) The first issue isn't a problem when a shared lib of libffi would +# be installed in system locations, but we do not assume that. So, +# when running in -dynamic mode, we must either install libffi to +# system locations ourselves, or we must add its location to +# respective environment variable, (DY)LD_LIBRARY_PATH etc...before +# we call dynamically linked binaries. Especially, the latter is +# necessary as GHC calls binary it produced before its installation +# phase.
