I'm sure that for 2) it's really worth the trouble, so the projects
should be contacted.
For 3) I'm not sure how this "-no-undefined" option went into the
build system. Maybe those projects just need to upgrade their
autoconf or automake?
For 1), I guess it is not worth the trouble, as the extra option
for the test programs doesn't really hurt anyone.
