Comment(by simonmar):
GHC is already following your suggestion: there is a copy of the gmp
library in the build tree that we use if there isn't one on the system.
It's in `libraries/integer-gmp/gmp`, and the same is true for `libffi`
(although for the latter the problem has been that we are ''always'' using
our copy of `libffi`, and some distros wanted us to use the system one
instead, which is what #5743 is about).
To avoid needing a hack, you just need to provide a stage 0 compiler that
has the right dependencies. You can get one by building GHC and then
making a binary distribution from it. Having done that, you're all set -
no need for `libgmp.so.3` symlinks.
