${libdir}/x86_64-linux-gnu/pkgconfig/.
Honor this setting when checking whether the module is installed.

Fixes flyspray 1100 for me.

[[Imported from SVN: r6746]]

- Remove unnecessary path to control file (It was needed for building
  installed modules which we do not do any more
- Test for ../../pkgconfig/$modname.pc to decide whether a module is 
  installed or not. Fixes flyspray 1100.

  do exist, as they are actually one file for installed modules.)
- Only build modules that are not installed
- Store relative path of CONTROL file and use it during running
  commands (on second thought I am not sure whether this is really
  needed).

Fixes flyspray 1112.
Please check whether flyspray 1100 is also resolved.

After review this should definitely be merged into the release branch.

This fixes FS 946.

- make sure that the module is not a local one before checking if it
  is installed
- fix FS#1100

according to the standard std::pair is a struct

No clue what that patch was supposed to due,
but it even slipped into dune 2.1.

Backported from Martin's development branch.

It is not standard conforming.

This file must have missed when deleting th backwards compatible code.

[[Imported from SVN: r6681]]

This patch removes the constructor from the overload set.
Before the constructor was there but failed to compile
due to the static assertion.

If you have methods f(K) and f(FieldVector<K,n>) with
n>1 the overload was ambigous when calling f() with
a FieldVector<K,1> because there is a conversion
from this to FieldVector<K,n> - even if it does not
compile due to the failing static assertion.

Now this is avoided using SFINAE. This fixes fs#1024.

a) it appears overly complicated.  Why not just use '=='?
b) it is never used anyway

[[Imported from SVN: r6647]]

so it matches the name of its source file.
