# We package libffi as Haskell package for two reasons:
# 1) GHC uses different names for shared and static libs, so it can
# choose the lib variant to link with on its own. 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. However, both mechanism, installing to system locations or
# modifying (DY)LD_LIBRARY_PATH, are already in place for Haskell
# packages so with packaging libffi as Haskell package we reuse
# them naturally.
