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.
