Add "compiles" keyword to cran.mk, updates ports.

TLDR: add compiles keyword to USES=cran for consistency.

While updating a R-cran port I got the following error:
Error: /usr/local/lib/R/library/tseries/libs/tseries.so is linked to /usr/local/lib/gcc48/libgfortran.so.3 from lang/gcc but it is not declared as a dependency
Error: /usr/local/lib/R/library/tseries/libs/tseries.so is linked to /usr/local/lib/gcc48/libquadmath.so.0 from lang/gcc but it is not declared as a dependency

To fix this I propose introducing a keyword to USES=cran to register the dependency on GCC.  In this patch I have also updated the two other ports that have manually introduced a dependency on gcc.  

The reason for this is to introduce consistency with the main R port.  Should the R port change what compiler it uses (for example, a specific version of gcc, or even clang) then there are only two locations that need updating: R and cran.mk.  Currently, one needs to update 1 + n, where n is the number of (unbounded) ports that need compilation.

Best would be to add a lang/R/compiler.mk that would be included in both lang/R/Makefile and Mk/Uses/cran.mk so that only one place needs to be changed.

  Mk/Uses/cran: add "compiles" argument.

  [1] Add "compiles" argument to cran to allow R-cran ports need to compile
  code to bring in the correct compiler dependencies.  Also, ensure
  consistency between the compiler selected by the R port and the R-cran ports.

  [2] Migrate R-cran ports that manually specify the compiler to
