Three versions are installed:
plumed - flags to link plumed (as in patch --shared)
plumedWrapper - flag to link plumed wrapper only (as in patch --runtime)
plumedInternals - flags to link full plumed library, including required CPPFLAGS

Notice that some macros are stripped from CPPFLAGS. This might
be improved in order to keep only the relevant ones.

This library contains only the wrapper/Plumed.o object and
can be used to link plumed with --runtime option without
incurring in linking errors when the MD code links PLUMED_LOAD
variables more than ones

A total of 5 travis jobs is run each time

See #286

refactor EDS documentation to fit into Camilloni submodule format, and add reference to new paper describing some features of the module (#293)

[makedoc]

Added in the list of options to be tested:
$($CXX --print-prog-name=ld) -r -o
As suggested by @alalazo

Since this option appears to work also with old compilers, I try
it as a first option.

See #291

Improvements in drr module

Spot out by cppcheck on master branch. Since the problem is relevant
also for v2.3, I fix it here.

This command should be more portable. Notice that with old
gcc (e.g. 4.6) this does not work. I added a test such that
when this does not work "ld -r -o" is tried instead

removed extra comma
