Bivand, Roger requested to merge roger.bivand/interp:master into master Aug 15, 2017

Added src/Makevars based on:

http://dirk.eddelbuettel.com/blog/2017/08/14/#009_compact_shared_libraries

For me:

CRAN 1.0.29 on Fedora 26, gcc version 7.1.1

$ ls -lh $R_LIBS/interp/libs/*.so -rwxrwxr-x. 1 rsb rsb 27M Jun 19 10:35 /home/rsb/lib/r_libs/interp/libs/interp.so

with src/Makevars on Fedora 26, gcc version 7.1.1

$ ls -lh interp.Rcheck/interp/libs/*.so -rwxr-xr-x. 1 rsb rsb 491K Aug 15 10:13 interp.Rcheck/interp/libs/interp.so

I don't have access to OSX, so can't check there.
