Hi,

Regarding this patch I have made the following changes.

Dropped using 'extra_objects' as it was buggy from the start and unified
hooks for static (.a) and dynamic (.so) libriaries.

Renamed static_first to search_static_first and set its default value to
0. If someone really needs it, let me know. Otherwise search_static_first
hooks will be removed in future. I find it quite useless because systems
prefer shared libraries to static libraries (if they are in the same
directory) and Python extension modules are always shared libraries
anyway and I don't believe in speed improvement when linking against
static libraries in this situation.

Applied. In addition, one can use also LAPACK and BLAS environment
variables.

Applied. In addition, updated comments in sample_site.cfg.

I'll look forward to scoreboard to see if my changes broke something,
especially in win32 platform.
