Comment(by simonmar):
bos: I'm looking at this and I'm not sure I agree with your original
suggestion, that we should record the full path name to the versioned
`.so` because the user may not have installed the appropriate `-devel`
package.
If the user has not installed the appropriate `-devel` package, then they
cannot link anything with GHC, so it seems reasonable that they would also
not be able to link anything with GHCi either. I don't think of GHCi as
doing "runtime linking", it's just doing ordinary linking, but storing the
result in memory for immediate execution instead of on disk.
So unless anyone persuades me otherwise, I'm going to implement the simple
fix I described above, which is to use `gcc --print-file-name` as another
strategy for mapping library names to file names in GHCi.
