- Link dynamically with libavcall, libpcre and libgmp and fix build on
amd64 (and optimistically sparc64 too)
- Remove the devel/libgetline dependency and don't link with libgetline:
While libgetline provides getline() it has an entirely different
signature than getline(3). This make the fgetline builtin function
unusable and causes e.g. the cat.scm example to segfault.
